Reconfigurable square microstrip patch antenna with polarization diversity

Single-feed Square Microstrip patch antenna with single notch for polarization reconfigurability has been proposed. Reconfigurability can be achieved by placing PIN diode within the notch. Simulation and fabrication of antenna is done by considering ideal diode that is diode size patch in place of PIN diode. An antenna can switch between Linear and Circular Polarization when diode is switched ‘ON’ and ‘OFF’ respectively.
