Abstract

A polarization reconfigurable spiral slot antenna with polarization states switched among left-hand circular polarization (LHCP), right-hand circular polarization (RHCP) and linear polarization (LP) is proposed in this paper. The antenna consists of a coplanar waveguide (CPW) input, a pair of reconfigurable CPW-to-slotline transitions, two separated same size single-arm spiral slot radiators, and four PIN diodes for reconfigurability. A good impedance match (VSWR≤2) for both linear and circular polarization is achieved from 2.1 to 2.9 GHz. The bandwidth for axial ratio AR≤3 dB for both RHCP and LHCP states ranges from 2.27 to 2.66 GHz (15%). The simulation and measurement results agree well and hence sustain the reconfigurability of the proposed design.
