## **1. Introduction** 

The AP.35A has been designed for embedded (inside device) integration with GPS receiver modules, the AP.35A combines a 35*35*3.5mm advanced low profile ceramic patch antenna with a one stage LNA and ultra thin coaxial cable. 

The Ground Plane size of 35*35mm combined with the larger size GPS Patch, gives this  solution a performance increase in gain of 1 2dB. It also helps shields the patch antenna from noise and increases performance at low elevations.. Taoglas active antenna modules utilise XtremeGain™ technology for the highest sensitivity in the industry. 

This antenna system consists of two functional blocks, the LNA portion and the patch antenna. The AP.35A has a back-end SAW filter.
