Abstract

A circularly polarized microstrip short back fire antenna (CPMSBA) with two ring corrugated rim using aperture coupling feed method is proposed in this paper. The antenna is designed to operate in KU-band. The simulation results verify the circular polarization. The axial ratio bandwidth bwAR is 3.74%, gain is 10.43 dBi and radiation efficiency is 89.7%. The antenna has a compact structure and high electrical and mechanical characteristics.
