Realization of circular polarized microstrip antenna with Arc-slot fractal geometry

Abstract

Arc slot fractal boundary microstrip antenna is proposed in this paper. A technique for realization of circular polarization with integration of Arc slot fractal boundary at peripheral of circular patch is presented. In the simulation, 10 dB return loss bandwidth of 38 MHz (1.68-1.718 GHz) and axial ratio bandwidth of 7.9 MHz (1.696-1.7039 GHz) obtained. Laboratory prototype has been fabricated and return loss bandwidth, axial ratio bandwidth, radiation pattern, etc were measured. The simulation and measured results are nearly match with each other.
