Abstract: A polarization reconfigurable antenna based on the reflective phase shifter is designed and implemented.The radiation element of this dual feed antenna is a pair of perpendicularly crossed bow-tie dipoles. In dual-feed network, the phase difference between two feed ports is adjusted through two phase shifters, to achieve left-hand circular polarization,right-hand circular polarization and linear polarization. Through the method of loading matching segments, the phase range of reflective phase shifter is extended and the phase accuracy of phase shifter is increased. The axial ratio of circular polarization can be improved through phase difference fine adjustment. The center frequency of this antenna is 5.4 GHz with measured 10 dB impedance bandwidth is 990 MHz, 760 MHz and 850 MHz in linear polarization, left hand circular polarization and right hand circular polarization, respectively. Moreover, the antenna maintains stable radiation patterns and the measured average gain is 5.3 dB with more than 27 dB polarization isolation. The measured results of this reconfigurable antenna are in good agreement with their simulated values.
