## 1. Introduction 

The CGGP.18.2.A.02 is a 18mm ceramic GPS/GLONASS/Galileo embedded passive patch antenna, with a 2mm low-profile. It is designed for vehicle telematic applications as well as other M2M/IoT devices. Typical applicable industries are transportation, defense, marine, agriculture, and navigation. 

The antenna has been tuned and tested on a 70 x 70 mm ground plane, working at GPS 1575.42MHz and GLONASS 1602MHz, with 3.23dBi gain and 3.53dBi 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 CGGP.18.2.A.02 is manufactured and tested in a TS16949 first tier automotive approved facility. Like all antennas, at least some detuning will occur when placed in a different device environment or on a different ground-plane. 

For large volume GPS/GLONASS/Galileo 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 length for these antennas, all subject to potential NRE and MOQ. For more details please contact your regional Taoglas customer support team.
