Perturbed Square Ring Slot Antenna with Reconfigurable Polarization

Description:
The invention is directed to an antenna with reconfigurable polarization, and more particularly, to an antenna having a perturbed square ring slot configuration for operating in multiple polarizations. Polarized (CP) antennas are popular choices in mobile wireless communications applications owing to their ability to allow flexible orientation between the transmitter and receiver antennas and to reduce multipath effects that can lead to signal fading. The ability to efficiently operate with both sense of CP (LHCP and RHCP) allows the system to reuse frequencies and double the system capacity. Moreover, if the antenna can be switched between two senses of CP as well as linear polarization, it will allow the user to roam to virtually any existing network.
