A polarization reconflgurable spiral slot antenna with polarization states switched among left-hand circular polarization (LHCP), right-hand circular polarization (RHCP) and linear polariza- tion (LP) is proposed in this paper. The antenna consists of a copla- nar waveguide (CPW) input, a pair of reconflgurable CPW-to-slotline transitions, two separated same size single-arm spiral slot radiators, and four PIN diodes for reconflgurability. A good impedance match (VSWR 6 2) for both linear and circular polarization is achieved from 2.1 to 2.9GHz. The bandwidth for axial ratio AR 6 3dB for both RHCP and LHCP states ranges from 2.27 to 2.66GHz (15%). The simulation and measurement results agree well and hence sustain the reconflgurability of the proposed design.
