This paper illustrates the use of active frequency selective surfaces (FSS) in reconfigurable antennas. A patch-form dual-polarized tunable FSS is adapted for use as an active artifi-cial magnetic conductor (AMC). As with the tunable FSS, the ac-tive AMC offers independent tuning capability of the reflection phases for two polarisations of incident EM waves. By combining the AMC with a wideband coplanar waveguide fed monopole an-tenna, circularly polarisation (CP) capability is realized at any fre-quency over the 1.15-1.60GHz band. Furthermore, the CP state can be switched between left hand CP and right hand CP, by simply interchanging the capacitances of varactors controlling the reflection phases of the two orthogonal polarised waves. The an-tenna covers the frequency bands of all operational and in-prepa-ration satellite navigation systems, including GPS, GLONASS, Beidou and Galileo. polarization reconfigurable circular polar-ized (CP) antenna using active artificial ground (AG) structure.
