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.
