SPECIFICATION Part No. : CGGP.18.4.C.02 Product Name : 18mm Ceramic GPS/GLONASS Patch Antenna, 1575-1610MHz Features : Wide-band Operation 18mm*18mm*4mm 3dBiC Peak Gain (on 70mm*70mm ground-plane) Pin type Automotive TS16949 Production and Quality Approved RoHS compliant SPE-11-8-098/D/SS Page 1 of 9 1. Introduction This 18mm ceramic GPS/Glonass patch antenna, by means of a double resonance design, has unique wide-band operation over the whole operating bands of GPS and Glonass systems from 1575MHz to 1610MHz. The antenna achieves best in class right hand circularly polarized gain with good axial ratio characteristics mitigating multi-path effects which is vital to improved S/N carrier ratio and faster locking times on the device itself. It is mounted via pin and double-sided adhesive. This antenna has been tuned for a centre position on a 70mm*70mm 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 centre or on different ground-plane sizes, custom tuned patch antennas can be supplied.
