Abstract

Microstrip patch antennas provide good compatibility with communication system's printed circuitry. Here a circular microstrip patch antenna with circular configuration of ground plane and substrate has been designed for GPS using a cavity line model. RHCP is obtained by placing coaxial pins quadraturly and symmetrically along the two main axes and pins are fed through a hybrid feed arrangement. Circular ground plane effect is investigated for return loss and VSWR, which are typical parameter used to study the behavior of antennas. The results obtained provide a workable antenna design for incorporation in GPS receivers.
