Introduction

This ceramic GPS patch antenna is based on smart XtremeGain™ technology. It is mounted via SMT

process and has been tuned as the optimal solution for the ublox C16-G25Q GSM/GPS Integrated

reference Design.

The C16-G25Q GSM/GPS reference design is a complete and integrated solution for telematics

applications such as fleet management, asset tracking, road pricing, and security/surveillance. It

demonstrates the integration of u-blox’ NEO-5Q GPS receiver with a LEON-G200 GPRS/GSM module.

This 100% SMD solution uses SMT passive GPS (Taoglas SGP.25D) and GSM antenna (Taoglas PA.25A)

and an on-board SIM Chip with activated phone number (SIM holder optional for mechanical (SIM).

On the test fixture of 63.2 x 50.03 mm (GND Plane) the antenna has a centre frequency of 1567MHz ±

3MHz
