This paper reports a reconfigurable patch antenna using a novel dual-slit perturbation for circular polarization diversity. The proposed antenna consists of the dual-slit with in- and out-slit at a diagonal corner and three identical single-slits at the residual corners for generating right- and left-handed circular polarization. By controlling two pin diodes mounted in the dual-slit, the size of the slit can be switched and circular polarization diversity can be achieved. The measured results of the implemented antenna which employed the dual-slit show a good agreement with the simulation results and demonstrate an excellent controllability of alternating circular polarization senses at the resonant frequencies.
