## **1. Introduction** 

The DSGP.1575.18.4.A.02 is an 18mm square ceramic GPS L1 / GALILEO E1 passive patch antenna. 18mm square with a height of just 4mm, this low profile antenna is ideal for space constrained applications in telematics devices, vehicle tracking/fleet management systems, wearables and navigation. 

The antenna has been tuned on a 50*50mm ground plane, working at 1575.42MHz with a 4.20dBi gain. The radiation pattern is broadly hemispherical with a stable gain across elevations. 

The ceramic patch is mounted via SMT process, ideal for high volume low cost assembly. It is manufactured and tested in a TS16949 first tier automotive approved facility. 

For further optimization to customer specific device environments, custom tuned patch antennas can be supplied, subject to NRE and MOQ. For more details please contact your regional Taoglas sales office.
