Abstract

The printed compound air-fed array (PCAFA) is an improved Fabry-Perot resonator (FPR) antenna, which exhibits better performance than traditional FPR antenna, by means of the non-uniform phase and magnitude of field distribution on aperture are partly compensated in design. In this paper a kind of circularly polarized (CP) PCAFA antenna is proposed and studied, in which the FSS cover is composed of square patches with tapered size and the HIS base is composed of mushroom-type rectangular patches with inversely tapered patch size. The CP radiation is generated by a simple conner-fed rectangular patch radiator which is embedded in the centre of the base. This CP PCAFA antenna owns the features of feeding simplicity, low-profile structure, high gain and high aperture efficiency. The design procedure and example is presented.
