## **1. Introduction** 

The CGGBP.25.2.A.02 is a ceramic GPS/Glonass/BeiDou passive patch antenna, with a low profile thickness of only 2mm. It is designed for applications in vehicle navigation devices as well as other M2M/IoT devices where space is at a premium. Typical applicable industries are transportation, defense, marine, agriculture, and navigation. 

The antenna has been tuned on a 70 x 70 mm ground plane, working at 1561MHz, 1575.42MHz and 1602MHz, with 3.44dBi gain, 3.25dBi gain and 4.35dBi gain, respectively. The low profile design makes this antenna perfect for applications where space is limited. It can be easily through-hole mounted on PCB via pin. Double sided adhesive on the bottom of the patch helps to keep it in place while undergoing mounting. The CGGBP.25.2. A.02 is manufactured and tested in a TS16949 first tier automotive approved facility. 

For large volume GPS/GLONASS/BeiDou projects where performance is paramount, tuning for customer specific device environment and ground-plane size is needed, so custom tuned patch antennas should always be used. Taoglas can also provide different pin lengths for these antennas, all subject to potential NRE and MOQ. For more details please contact your regional Taoglas sales office.
