## **1. Introduction** 

The DSGP.1575.12.4.A.02 is a ceramic GPS L1 / GALILEO E1 passive patch antenna. 12mm square and with a height of just 4mm, this antenna is perfect for applications in compact telematics devices, vehicle tracking/fleet management systems, wearables and navigation devices. 

The antenna has been tuned on a 50*50mm ground plane, working at 1575.42MHz with a 2.73dBi gain. The ceramic patch is mounted via SMT process, suitable for high volume low cost assembly. 

The antenna is manufactured and tested in a TS16949 first tier automotive approved facility. 

Small antennas should ideally be custom tuned for the device environment, Taoglas offers this service subject to NRE and MOQ. For more details please contact your regional Taoglas sales office.
