1. 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 ?
