Polarization-Switchable Magneto-Electric Dipole

A polarization reconfigurable magneto-electric (ME) dipole antenna is presented. The ME dipole is fed by a pair of dipoles crossed through a 90° phase delay line. By controlling the state of the four p-i-n diodes that inserted in the crossed dipoles, the antenna can switch the polarization between LHCP and RHCP. A wide band and good radiation patterns can be realized by the proposed simple structure.
