Summary:
In this paper, an antenna with polarization reconfigurability is presented. The antenna consists of a two cross-slots diagonally positioned in the centre of a circular patch antenna. Two pair of switches are placed in the slots and by controlling the length of the slots, three different polarizations can be reconfigured. The proposed antenna is capable to reconfigure between linear polarization (LP), right-hand circular polarization (RHCP) and left-hand circular polarization (LHCP). The linear polarization is achieved when the lengths of both slots are equal and the circular polarization type is obtained due to the inequality of the slot length. Details of the design and simulation results are discussed. This reconfigurable antenna with polarization diversity can be used for wireless local area network (WLAN) application.
