Abstract:

A simple method is proposed to signifi cantly enhance the broadside directivity of a simple slot antenna over a wide bandwidth. This improvemen t is achieved by introducing a simple optimised dielectr ic superstructure with an axial variation of permittivity. In this antenna, both the superstructure and ground plane are cylind rical in shape with an area of 1.62λ02. The antenna has a measured peak directivity of 18.1 dBi and an extremely wide 3 dB directivity bandwidth of 51.1%. A WR-75 waveguide is used to feed the slot antenna. The antenna is well matched over the entire directivity bandwidth, which extends from 8.75 to 14.75 GHz. The measured average aperture effi-ciency is ∼88% over the 3 dB directivity bandwidth.
