E-shape microstrip patch antenna design for GPS application

The area of micro strip antennas has seen some inventive work in recent years and is currently one of the most dynamic fields of antenna theory. In this research, E-shape microstrip patch antenna has been designed for GPS application (GPS L2 1227.5 MHz band) and covering the 1200 to 1280 MHz frequency band. Simulated results for main parameters such as return loss, impedance bandwidth, radiation patterns and gains are also discussed herein. The study shows that modeling of such antennas, with simplicity in designing and feeding, can well meet GPS application. A designed antenna for the GPS application at the civilian GPS frequency (1227.5 MHz) has been simulated. Two parallel slots are incorporated to perturb the surface current path, introducing local inductive effect. This antenna is fed by a coaxial probe feeding.
