## **1. Introduction** 

The CGGP.25.4.E.02 is a 25*25*4 mm embedded ceramic GPS/GLONASS/GALILEO Patch antenna. It features a double resonance design at GPS/GALILEO and GLONASS bands, 1575.42 MHz and 1602 MHz respectively. This antenna has been tuned for a center position on a 70mm *70mm ground plane. Return loss is -28 dB at 1575.42MHz and -22 dB at GLONASS. Overall the antenna has greater than 60% efficiency. 

For further optimization to customer specific device environments where positioning is off center or a different ground-plane size, custom tuned patch antennas can be supplied.
