Design of Circular Polarization Microstrip Antenna with Array 4×4 Elements for Microwave Radio

Abstract

This paper proposes the design of a circular polarization microstrip antenna (CPMA) which is optimized using array 4×4 element for microwave radio applications. The bandwidth generated from the proposed antenna is 1559 MHz with a frequency range 9862 MHz – 11241 MHz. The simulation results from AWR Microwave Ofiice 2009 shows that the array CPMA has worked at a center frequency of 10700 MHz with a return loss of −26.57 dB, VSWR of 1.098 and axial ratio (AR) 2.031 dB. This shows that the proposed antenna produces a suitable bandwidth requirements for microwave radio communication systems.
