SPECIFICATION Part No. : CGGP.35.3.A.02 Description : 3.5mm thick GPS/GLONASS/GALILEO Patch Antenna, 1575/1610Mhz Features : Wide-band Operation 35mm*35mm*3.5mm 4dBi Peak Gain (on 50mm*50mm ground-plane) 85% Efficiency (on 50mm*50mm ground-plane) Pin type Automotive TS16949 Production and Quality Approved RoHS Compliant -SPE-16-8-062/J Page 1 of 13 1. Introduction This 35mm ceramic GPS/GLONASS/GALILEO patch antenna, by means of a double resonance design, has unique wide-band operation over the whole operating bands of GPS/GALILEO and GLONASS systems from 1575MHz to 1610MHz. It is mounted via pin and double-sided adhesive. This antenna has been tuned for a center position on a 50mm*50mm ground-plane. It is manufactured and tested in a TS16949 first tier automotive approved facility. For further optimization to customer specific device environments where positioning is off center or on different ground-plane sizes, custom tuned patch antennas can be supplied. Taoglas can also provide different pin lengths for these antennas, subject to potential NRE and MOQ.
