Polarization reconfigurable CPW‐fed square slot antenna using pin diodes

A novel reconfigurable coplanar waveguide (CPW)-fed square slot antenna with switchable polarization is presented. The proposed antenna is fed by a CPW, with two T-shaped metal strips connected to ground plane using pin-diodes. Switching between right-hand circular polarization (RHCP) and left-hand circular polarization (LHCP) is achieved by turning the pin-diodes on or off. The designed antenna is implemented and measured. It shows that the proposed antenna has broad CP bandwidth in both RHCP and LHCP states. © 2007 Wiley Periodicals, Inc.
