    Abstract

    A novel square patch antenna with reconfigurable circular polarization (CP) is presented in this letter. A circular slot with perturbation is placed beneath the patch. The circular slot that has an inner perturbation yields right-handed CP, but with an outer perturbation slot yields left-handed CP. Experiments show an antenna gain of 2.8 dBic and a 3- dB axial ratio bandwidth of 30 MHz which well match the corresponding simulation results. Copyright
