A simple design of a wideband circularly polarized (CP) reconflgurable antenna is proposed. The primary radiator consists of two orthogonal straight dipoles while a dual-cavity structure is employed to significantly enhance the overall CP performance of the antenna. The polarization reconfigurability is realized by electronically switching the ON/OFF states of two PIN-diode pairs. Thus, the antenna can radiate CP wave with either rotating senses. The proposed design exhibits a wide simulated impedance bandwidth (BW) of 70.8% and an overlapped axial ratio (AR) BW of 58.5%. In addition, the antenna realized gain is greater than 7.2 dBi and its radiation efficiency is around 90% over the overlapped BW. © 2018 IEEE.
