The MA210 Optimus is a dual-band, adhesive-mount Wi-Fi MIMO antenna with high efficiency in both the 2.4 GHz and 5/5.8 GHz bands. The MIMO capabilities of this antenna allow for increased channel capacity and reduced transmitting power, making it an excellent choice for high-speed wireless applications. The MA210 Optimus comes in a quality, low-profile housing with high-grade 3M double-sided tape for quick and easy mounting on glass, plastic, or even out of sight under a dashboard. It is rated IP67 for water resistance.
Many module manufacturers specify peak gain limits for any antennas that are to be connected to that module. Those peak gain limits are based on free space conditions. In practice, the peak gain of an antenna tested in free space can degrade by at least 1 or 2 dBi when put inside a device. So ideally you should go for a slightly higher peak gain antenna than mentioned on the module specification to compensate for this effect, giving you better performance.
Upon testing of any of our antennas with your device and a selection of appropriate layout, integration technique, or cable, Taoglas can make sure any of our antennas’ peak gain will be below the peak gain limits. Taoglas can then issue a specification and/or report for the selected antenna in your device that will clearly show it complying with the peak gain limits, so you can be assured you are meeting regulatory requirements for that module.
For example, a module manufacturer may state that the antenna must have less than 2 dBi peak gain, but you don’t need to select an embedded antenna that has a peak gain of less than 2 dBi in free space. This will give you a less optimized solution. It is better to go for a slightly higher free space peak gain of 3 dBi or more if available. Once that antenna gets integrated into your device, performance will degrade below this 2 dBi peak gain due to the effects of GND plane, surrounding components, and device housing. If you want to be absolutely sure, contact Taoglas and we will test. Choosing a Taoglas antenna with a higher peak gain than what is specified by the module manufacturer and enlisting our help will ensure you are getting the best performance possible without exceeding the peak gain limits.
