GPS Receiver Front-End Circuit Layers 1.575 GHz LNA and Antenna Design

Abstract

GPS is used in many areas nowadays is the Global Positioning System. Founded in GPS for military purposes was opened for civilian use later. Satellite-space, control and user segment consists of 3 segments. The GPS receivers are electronic circuits for the reception of signals from this system. GPS receiver front-end circuit is composed of three layers. These layers; GPS antenna, low noise amplifier (LNA) and the second stage amplifier. In this study, the maximum gain with minimum reflection is designed to 1.575 GHz helical and microstrip simulation studies on two GPS antenna is made.
