摘要：

A pattern diversity antenna, loaded with dielectric phase correcting structure is investigated. Antenna system is fed through monopole, which is surrounded by reconfigurable frequency selective reflector (RFSR). Each RFSR is connected to ground plane via switch. In ON state of switch corresponding RFSR behaves as reflecting surface, whereas it'll become transparent for the OFF state of switch. Thus beam steering can be achieved along the entire azimuth plane by configuring the switching states. Dielectric phase correcting structure (PCS) is incorporated in the direction of beam for transforming non-uniform phase distribution of vertically polarized electric field to nearly uniform phase distribution, which in turn enhances the gain of unloaded antenna by 1.5-2.0 dBi. The simulation has been carried out for ISM band (fr= 2.45 GHz) using CST Microwave studio software.
