Connected Cars Place New Demands on Vehicle Electronics Design

By Chris Anderson, CTO, Taoglas. Article featured in Wireless, Design & Development Magazine, Vol. 25, No. 5 

The connected car of the future will have more options than ever, expanding beyond basic infotainment and navigation systems to offer the latest in safety features, and (in the-nottoo-distant future) autonomous driving. The requirement for more sensors and antennas to deliver high-bandwidth, low-latency connectivity is seemingly at odds with another requirement of auto manufacturers—fewer cables and connectors that cause noise and vibrations, while being complicated and expensive to install. In today’s connected cars, antennas and electronics are increasingly being forced in closer proximity. What does that mean for design engineers?

For a modern car, electronics represent a little more than 30 percent of the vehicle’s total costs, and that percentage is expected to rise.  The more electronics a vehicle deploys, the greater need for electrical power, system components, and need to interconnect those system components. Electronic connections (be it the power supply or control wiring harness), digital communications connections, or radio frequency (RF) interfaces add complexity, cost, and weight.

Automotive designers spend considerable effort to minimize these factors. Consumer expectations are such that even base model vehicles are now expected to have features like smartphone connectivity via Bluetooth, entertainment, and safety systems like the Event Data Recorder or European eCall. Hence, significant design efforts are required in this area every time for all models. Old cars dealt with the power and control needs of facets like power windows and seats, using very complicated discrete wiring systems. Their weight and cost kept these features in premium vehicles.

Bosch created the Controller Area Network (CAN) bus in the mid- 1980s to address these issues. Today, CAN allows for power and communications using simpler and cheaper connectors and wiring. Some new car features such as the entertainment center, cameras, and cellular/Internet connectivity, use variations of USB and Ethernet. However, none of these address the need to run radio signals around the car. The GNSS receiver, eCall cellular radio, SiriusXM receiver, new DSRC radio (for talking to other cars and roadside infrastructure), maintenance cellular radio, remote keyless entry radio, and tire pressure monitoring system receiver all need RF cabling, connectors, and antennas.

Strategies For Elegance

The first step in simplifying vehicle interconnects was the use of a multi-drop digital data bus instead of discrete wires.  The next major step has been to consolidate functions into clusters of electronics. This often includes radio communications devices like GPS or cellular radio systems. One trade-off is how antennas for the radios in question often need to be remotely mounted elsewhere in the car for an appropriate radiation pattern to communicate with the radio link’s other end. GNSS or SiriusXM obviously need a clear view of the sky to see satellites, while cellular antennas need a clear view of the horizon.

This is where physics starts to complicate matters. Running radio frequency signals around a car from a radio and antenna is normally accomplished with coaxial transmission line cables. The thinner and lighter those cables are, the cheaper and more flexible they become. Unfortunately, this also means sacrificing performance and introducing more signal loss, which is proportional to both frequency and length of the cable.

In the case of GNSS, this situation can be easily addressed using an active antenna. The GNSS antenna contains a receive filter and Low Noise Amplifier (LNA), which is powered by a DC voltage over the coax cable. This removes the coaxial cable losses and helps retain the best possible performance. While this is normal practice for GNSS and SiriusXM receive-only systems, the process is increasingly difficult to do with radio systems that are bi-directional and also transmit, such as cellular, WiFi, and Bluetooth.

The filter and LNA added to a receive-only radio are duplications of parts already in the receiver.

In that context, they’re an added expense over what would be needed if the coax losses were low enough. For a radio that transmits, however, this sort of solution would require transmit and receive filters, a transmit power amplifier big enough for the signals in question, the receive LNA, a pair of RF switches, a power supply system, and dedicated transmit/receive control signal from the remote radio.

This, in turn, would require a coax cable between the radio, its active antenna, and also a control signal cable. Just as with GNSS, all this is already built into the cellular radio, so it’s a lot of extra expense and complication to mitigate coax losses. Therefore, it’s very rare to see an active antenna for a cellular system because of the added cost. The brute-force way of dealing with coax losses in cellular or other transmitting radios is often to use lower loss, higher-quality coax as the transmission line. There are trade-offs, however, in that the higher-performance coax is thicker, heavier, stiffer, and expensive.

Antennas Of The Future

The trend of co-locating the radios and their antennas will only continue, as the cost, weight, complexity, and RF performance benefits far outweigh the added design and development complexity. In some cases, however, as additional antennas are added, a certain minimum separation between antennas is required. This is likely to push most antennas into a single area of the car. It will also require that an antenna deployment area will take up more space. An example here would be the need to have four cellular antennas, GNSS, DSRC, SiriusXM, and two WiFi antennas all located in a single enclosure on the roof of a car. Car designers are not likely to accept the 400-mm diameter dome that would be the optimal size solution for this, so a lot of effort will go into understanding the complex interaction of co-locating all these antennas and the radios that use them. Some antenna companies have already been doing this sort of product for other markets. While it would be nice to get all the car antennas into a single package, some smaller number of antennas will still need to be located away from the main antenna cluster with coax; for example, AM/FM antennas, because of their size and the common need to have two of them for receive diversity. Another example would be cellular antennas that need to be physically separated to ensure maximum MIMO throughput performance. Even in these cases, it’s most likely that the radios in question would still get integrated into a TCU-type solution and the location of the antennas constrained to somewhere that keeps the coax runs short. Longer term, it would make sense to create a digital interface standard for the FM broadcast radio, GNSS, and other radios such that the radios could be integrated directly with their antenna. This would allow those radio and antenna units to be distributed around the car wherever the vehicle designer has a place to put them that lines up with the radio’s performance need while also minimizing the use of coax cable and RF interconnects. The connections would be limited to high-speed digital data and power, and the lower-cost wiring and connectors that involves. One trend that’s already in discussion is running power and communication over the same wires. Historically the power system in a vehicle was viewed as being so noisy that to make any attempt at communication over the same wires would be highly unreliable. Using new digital spread spectrum communication techniques, viable solutions have already been created that could one day allow the interconnection of vehicle systems with only two or even one wire(s).

Go Where the Antennas Are

As the number of radio systems in cars grow, a better overall solution to the coax issues is to simply locate the radios very close to their antennas. This has resulted in the radios moving into a combined electronics package. An example of one is called a Telematic Control Unit (TCU). The TCU is then physically located near the antennas, wherever they’re placed on the vehicle.

This has a number of effects:

  1. The longer runs of coax cables that used to go from the radios to the antennas are now effectively replaced with cheap digital communication wiring between the TCU and rest of the car systems.
  2. Active antennas are no longer needed because the transmission lines between radio and antenna are so short, their losses are negligible.
  3. The antennas all need to be in roughly the same area of the car, or the above benefits are lost.
  4. Co-locating radio antennas creates a greater possibility for interference between the radio systems that must be carefully designed around. When the antennas were farther apart, this issue could often be ignored.
  5. Co-locating the radio electronics near their antennas creates more opportunity for RF emissions from those electronics to interfere with radio reception performance. This requires additional design effort and testing.

This co-location of TCU electronics and antennas also creates a need for new RF interconnects. While using a small, short coax cable to connect the TCU radios and antennas is an obvious solution, all those connectors are potential long-term failure points. When there can be up to eight or 10 coax connections between a TCU and its antenna system, there is also potential for assembly mistakes and a non-trivial amount of assembly labor costs.

Most RF connector systems haven’t changed for decades. It’s uncommon having to connect an array of eight to 10 RF feeds between two electronic boards in a small physical space. As such, there haven’t been a lot of products to meet this need, especially in a low-cost, high-density, highvibration environment. Most of these interfaces are still proprietary custom solutions not commonly available off the shelf. Since both sides of such an RF connector interface are specific to the product to which they’re being deployed, there’s no driving need for an interconnecting standard. A generic solution for this application is a current point of research for connector and antenna companies so that future products can simply reuse a known good solution.

One of the most interesting areas of investigation is the use of a selective axis of conduction elastomer materials to create PCB board-to-board interconnects with what looks like a simple layer of rubber. There are still significant issues to be solved, such as insertion losses, isolation, and cross-talk, but the concept looks promising.

The state-of-the-art in cabling for automotive electronics focuses on minimizing the number and length of all cables in the vehicle. This has led to consolidation of the electronics into packages with similar physical needs in the car. The future of cabling in cars will continue to push towards higher-speed data buses and minimizing interconnects other than power and data. This all conspires to further complicate the design and test of the vehicle electronic systems. That additional complication highlights the need for experienced expert partners when it comes to specialties like radio electronics and antennas.

Taoglas Launches High-Precision, Multiband GNSS Antennas

Courtesy of Taoglas

New antenna range includes L1/L2 and L1/L5 to help enhance RF performance for applications that require highly accurate location capabilities, including Connected Car

SAN DIEGO, California – September 07, 2017 – Taoglas, today launched a range of multiband high-performance GNSS antennas specifically designed to power the next generation of applications that require highly accurate location capabilities, including navigation, unmanned aerial vehicles (UAVs), precision heavy equipment, surveying, agriculture, and paving the way for the rise of autonomous vehicles. The new antenna range is the most comprehensive series of high-precision GNSS antennas in the market today, and incorporates several new form factors to help drive optimal performance and location capabilities across a wide variety of use cases.

To deliver the best accuracy, centimeter-level positioning and precise location capabilities required for applications like the Connected Car and autonomous driving, the use of multiple RF bands is required. Taoglas’ new range includes systems and antennas that utilize not only the additional functions of Galileo, GLONASS and BeiDou satellite systems, but also the GPS L1 and L2 or L1 and L5 bands to deliver the highest levels of accuracy and performance required.

“Today’s connected devices and applications demand new ways of approaching the age-old problem of location accuracy,” said Dermot O’Shea, Taoglas co-CEO. “In certain applications, there is simply no room for positioning errors—extremely precise location accuracy is an absolute requirement. To meet these demands, Taoglas has completely rethought the design process for GNSS antennas, delivering the industry’s most comprehensive range of high-performance GNSS antennas in a variety of form factors to best meet the application’s requirements.”

The new antenna range includes:

  • The GRS.10, a “smart” antenna that includes a high-performance GNSS (GPS, GLONASS, Galileo, BeiDou) ceramic antenna integrated with a u-blox NEO-M8U module. The integrated antenna removes additional loss brought on by the coaxial cables of external antennas, which results in better signal quality and acquisition times. This allows for longer cable runs during installation without degrading signal performance. The GRS.10 is an ideal product for installations in which a standard antenna cannot get a good view of the sky without a long cable run.
  • The Torpedo series GNSS quadrifilar helical antennas, extremely high-performance wideband satellite antennas for position-information-critical applications. The wide gain and axial ratio beamwidth provide excellent reception and signal fidelity across the sky. No other GNSS antenna provides such high circularly polarized antenna gain across such a wide beamwidth. The form factor is suited for base stations, telecommunications equipment, and other use cases such as remote monitoring. These are available in a passive (QHA) or active (AQHA) versions.
  • The BOLT A.90.A.10451111, a new GNSS timing antenna that includes lightning-induced surge protection and is an ideal solution for the base station market. The advantage over existing timing antennas is the addition of GLONASS and BeiDou It exhibits excellent out-of-GNSS-band rejection while maintaining a low noise figure, and comes in a through-hole mount IP69 and IP67 format.

The complete range of precision GNSS antennas also includes:

  • The ASFGP.36A.07.0100C, a ceramic GPS L1/L2 low-profile, low-axial-ratio, embedded stacked active patch antenna. The additional capability to also utilize L2 signals with a compatible receiver can greatly improve the reliability of a GPS fix in urban areas, and also delivers better signal reception with more satellites acquired, and a quicker time to first fix. By stacking the antennas in an innovative wedding cake style, the form factor is compact for vehicles and UAVs, yet provides the best performance for GNSS by optimizing axial ratio.
  • The MAT.12A a GPS/GLONASS/BeIDou dueling-loop chip antenna evaluation board, delivers the advantages of a circularly polarized patch antenna, with two miniaturized low-profile chip antennas on a smaller PCB footprint, at one-fifth the weight. Two linearly polarized chip antennas are used, and instead of relying on the geometry of the antenna to deliver circular polarization, it is enforced through the use of a hybrid coupler, which ensures that the power delivered to both antennas is always the same in magnitude and always 90 degrees separated in phase.

Yesterday, Taoglas also launched an industry-first range of small-form-factor ultra-wideband (UWB) antennas specifically designed to work with Decawave chipset and module solutions for applications including asset tracking, follow me drones, healthcare monitoring, smart home services, and other applications that demand high-performance indoor localization capabilities.

The flex and chip UWB antennas work with the DecaWave DW1000 chip for specific indoor positioning applications

SAN DIEGO, California – September 6, 2017 – Taoglas, a leading provider of IoT and M2M antenna products, today launched an industry-first range of small-form-factor ultra-wideband (UWB) antennas specifically designed to enable centimeter-level positioning and angle-of-arrival applications, including asset tracking, follow-me drones, healthcare monitoring, smart home services, and other applications that demand high-performance indoor localization capabilities. The antennas offer high efficiencies across a wide spectrum of frequency bands from 3GHz to 10GHz.

Indoor wireless positioning has long been hampered by technologies that were not designed for this purpose, such as Bluetooth, Wi-Fi and assisted GPS. UWB is a low-power digital wireless technology that offers significant increases in location precision and range while transmitting large amounts of digital data short distances over a wide spectrum of frequency bands. UWB’s low-power requirements offer increased battery life of sensors and tags, leading to reduction in overall operational costs.

Taoglas’ range of UWB antennas, designed in Taoglas’ Munich, Germany, engineering center, features both state-of-the-art flexible and rigid PCB embedded UWB antennas as well as UWB embedded SMT chip antennas. The flexible FXUWB range of antennas were developed utilizing a simple “peel and stick” assembly process, attaching securely to non-metal surfaces via 3M adhesive, with a highly flexible micro-coaxial cable mounting. There is also a version in a rigid PCB format, if desired. The UWB chip antennas are designed to be surface mounted directly onto a PCB. Both series of antennas help designers future-proof devices, keeping costs low while covering all common UWB commercial bands.

“Today’s emerging applications require very precise indoor localization of assets, objects and people,” said Ronan Quinlan, co-CEO, Taoglas. “UWB can work as a type of ‘indoor GPS’ to help solve the precision dilemma for indoor applications, bringing much greater levels of precision than current technologies. We optimize complex antenna performance parameters such as the Group Delay, Polarization and Fidelity Factor. Taoglas’ first-to-market line of UWB antennas are designed to help our customers capitalize on this need for real-time precision localization, with the quality, reliability and flexibility they’ve come to expect from working with Taoglas. One particular antenna we co-developed exclusively with DecaWave is the UWCCP.01 circularly polarized chip antenna, the first mass-market antenna specifically designed to enable a new generation of autonomous applications.”

The UWB antennas were designed for use with the DecaWave DW1000 chip, and are also compatible with any other UWB sensor modules on the market. Since its launch in December 2013, more than 3.5 units of the DW1000 have shipped across multiple industries. From real-time location of people and assets in factories, hospitals and mines, to automotive keyless entry systems, to drones, connected home and sports, the accurate location and secure communications capability of the DW1000 has already taken numerous applications to new heights.

“Antennas play a key role in our customers’ applications. Performance is a given for customers, but the capability to adapt to the constraints of the applications—size, shape, electronics environment—is equally important as end products get smaller and smaller. DecaWave is really pleased to partner with Taoglas, as their expertise is not only in delivering high-performance, off-the-shelf antennas, but also to provide customization services that will be highly beneficial to our customers,” said Ciaran Connell, CEO and co-founder, DecaWave.

Taoglas’ 25*25mm AGGBP.25B is a two-stage 28 dB Active GPS Patch Antenna Module that provides positional accuracy in a small form factor that is ideal for a performance monitoring solution like the Apex, which embeds the antenna in a small, fist-sized device called the Apex Pod in or under the players’ jerseys.AGGBP.25B GPS-GLONASS-BeiDou 2 Stage Active Patch

“A wearable device with accurate GPS location measurement is of paramount importance to monitor player performance, and the Taoglas antenna is a key component delivering this,” said STATSports CTO, Arthur McMahon. “We have found the Taoglas antenna gives us the best performance in GPS reception in the demanding environments of elite player performance analysis. The accuracy, reliability and robustness of their antenna in our harsh operating environments were key factors in choosing Taoglas.”

The Apex utilizes multiple channels and synchronized mesh networking to deliver data streams from all the players on the field to the Apex Software for analysis. The Apex delivers GPS speed and positional data, heart rate variability, digital compass, gyroscopic and accelerometer data; transmitting over half a million numbers every minute during training and games for a squad of more than 30 players.

Highly accurate positioning is critical, and Taoglas was able to help STATSports deliver location accuracy within 1 meter. However, with that many antennas and transmissions in close proximity, interference can be an issue. Taoglas’ solution includes a front-end SAW filter in front of the two-stage LNA to reduce out-of-band noise, such as signals from nearby cellular transceivers.
STATSports’ proximity to Taoglas’ Wexford, Ireland, headquarters and development labs means the teams can collaborate easily on new functionality as STATSports develops increasingly advanced performance tracking solutions.

“Having the best antennas in the industry can help STATSports collect the most accurate possible data on player performance,” said Dermot O’Shea, co-CEO of Taoglas. “In devices that small and sensitive, antennas can be the most common point of failure in the communications chain. Taoglas has the expertise to deliver reliable antenna solutions that can excel even in the most challenging of situations.”
