GPDF254.A GPS/GNSS Antenna by Taoglas

The GPDF254.A from Taoglas is a Passive GNSS L1 Patch Antenna that covers the GPS L1, GLONASS G1, Galileo E1 and BeiDou B1 Bands. It operates at 1561, 1575.42, and 1602 MHz with a gain of 1.4 dBi, 3.1 dBi and 1.7 dBi respectively. This RHCP antenna uses a dual-feed configuration to obtain an optimal axial ratio of more than 0.7 dB.

The GPDF254.A measures 25 x 25 x 4 mm and is available with 2.4 mm pin configuration. It is ideal for next-generation GNSS devices that require excellent positional accuracy in a small form factor. This antenna can be used in navigation systems, UAVs, robotics & autonomous vehicles, transportation & telematics, precision agriculture and RTK systems applications.
