Design and Simulation of Capacitive Fed Microstrip Antenna for GPS Applications
In this paper, a wideband circularly polarized capacitive fed microstrip patch antenna is proposed. It is a square patch antenna truncated in opposite corners, suspended above the ground plane. The antenna structure contains capacitive feed strip which is fed by coaxial probe. The proposed structure is designed and simulated to cover the entire frequency of GPS (Global Positioning System), i.e., L1 (1.575 GHZ), L2 (1.227 GHZ) and L5 (1.176 GHZ). The design and simulation of antenna is done using CST MW STUDIO.
