Wideband Polarization Reconfigurable Differential Circularly Polarized Antenna
This paper presents a polarization reconfigurable differential circularly polarized (PRDCP) antenna with wide impedance and axial ratio (AR) bandwidth for right-hand circular polarization (RHCP) or left-hand circular polarization (LHCP).The antenna is composed of a bandwidth-improved radiator and a reconfigurable differential-to-single-ended sequen
