A novel design of a microstrip patch antenna incorporated by two orthogonal L‐shaped switchable slots is proposed to achieve circular polarization. Two pin diodes are inserted into these L‐shaped slots and by making these two pin diodes ON and OFF the antenna can radiate with either right handed circular polarization or left handed circular ... A Survey on Polarization Reconfigurable Patch Antennas Polarization diversity with switchable polarization is used in order to reduce fading in wireless local area networks (WLANs), as a modulation scheme in radio frequency identification (RFID) systems, and to increase the security complexity in military wireless systems. Fully polarization reconfigurable antenna systems RECONFIGURABLEMICROSTRIPPATCHANTENNA ... radiation of the antenna is generated by two orthogonal modes at a same resonant frequency,the frequency offset phenomenon which often happened to antennas with switchable polarization can be avoided.

A proximity-fed patch with cross slots can switch polarization states among two orthogonal LPs and right-hand CP (RHCP) [7]. A square ring slot with the center part being perturbed is “Perturbed square-ring slot antenna with reconfigurable polarization,” IEEE Antennas Wireless Propag. Lett., vol. 8, … A reconfigurable slot antenna with switchable polarization ... Abstract: A novel reconfigurable slot antenna architecture allowing polarization switching is presented. The antenna shape consists of a slot-ring with perturbations which are switched on and off using pin-diodes. Two antennas allowing switching either between linear and circular polarization or between two circular polarizations are demonstrated.

Abstract: This paper proposes a reconfigurable multiband extended U-slot antenna with polarization diversity for wireless applications. The antenna is able to switch among linear polarization (LP) and left-hand (LH) and right-hand (RH) circular polarizations (CPs) for 2.4-/5.8-GHz wireless local area network (WLAN) systems.
