In this paper, a polarization reconfigurable microstrip antenna, for WLAN applications, is proposed. The antenna structure is based on a reconfigurable feed network, which drives a circular patch. The approach, presented herein, is based on electronically reconfiguring the phase difference, between the antenna's feeding ports, to achieve polarization diversity. The proposed antenna is designed and simulated using Ansoft HFSS, a Finite-Element-Method based EM solver. The computed return loss, for each case, is better than 10 dB over the 2.4─2.484 GHz frequency range. A prototype of the designed antenna is fabricated and measured. A good analogy between measured and simulated S11 plots is witnessed. For each switching condition, the radiation pattern, axial-ratio and peak gain of the antenna are included herein.
