Design of circular polarization microstrip patch antennas with complementary split ring resonator

摘要

A novel design of circular polarization microstrip patch antenna based on the complementary split ring resonator is evaluated numerically and experimentally verified. Unlike the previous application of its resonant performance, the non-resonant property of complementary split ring resonator is used as an asymmetric perturbation to excite the square microstrip patch antenna for a good circular polarization radiation. Good agreement is observed between the measurement and simulation results.
