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. For more details
