A reconfigurable antenna employing wideband frequency agile patches with simultaneous polarization reconfiguration is presented under the article. An antenna consists of a square microstrip patch which is connected to a square microstrip ring by using four varactor diodes (variable capacitor diode). These varactor diodes are used to achieve frequency reconfigurability between 1.6GHz to 2.4GHz (frequency agility bandwidth= 40%, S11 <= -10 dB). Employing two orthogonal feed points on the radiator enables switching amongst four polarizations states (two linear and two circular polarizations). These two feed points on the radiator can be excited by polarization feed network (PFN). PFN consists of a Wilkinson Power Divider and Schiffman 90° phase shifter. The simulated results agree reasonably well. © 2017 IEEE.
