✦ Synopsis
This article presents a polarization reconfigurable slot antenna with compact feed. Fed by dual modes of coplanar waveguide, a dual orthogonal linear polarization is excited in the slot and controlled by two PIN diodes. The proposed antenna has been built and its reflection coefficient, radiation pattern, gain were tested. The capacity performance in an indoor wireless local area network scenario was measured by using two proposed antennas as access point in a 2 Â 2 multi-input multi-output system. The results show the advantage of polarization reconfigurable antennas in channel capacity, especially at the condition of non-line-of-sight.
