## **1. Introduction** 

The SGGP.12.4.A.02 is a ceramic GPS/GLONASS/GALILEO passive patch antenna with low-profile thickness of 4mm. It is designed for applications in navigation devices, vehicle tracking/fleet management systems, and telematics devices. Typical applicable industries are transportation, defense, marine, agriculture, and navigation. 

The antenna has been tuned on a 50 x 50 mm ground plane, working at 1575.42MHz and 1602MHz, with a 2.67 dBi gain and 2.94 dBi gain, respectively. The ceramic patch is mounted via SMT process. It is manufactured and tested in a TS16949 first tier automotive approved facility. 

For customer specific device environments, custom tuned patch antennas are highly recommended, subject to potential NRE and MOQ. Contact your regional Taoglas sales office for details.
