High-gain, low-cost, planar antennas have attracted a lot of interest in recent years, with
regard to applications as fixed wireless access, satellite reception and various point-to-point
radio links. Microstrip patch arrays have primarily been good candidates, but the complex
feeding mechanisms degrade the antenna performance. A method of producing a high gain
planar antenna with a simple feed has been proposed in an earlier study. This technique
utilises a partially reflective surface (PRS) to introduce a leaky wave and beamforming
effect when placed in front of a waveguide aperture in a ground plane. The partial reflection
can be obtained from periodic arrays, also referred to as Frequency Selective Surfaces
(FSSs) when used for their filtering properties. The research effort in this thesis focuses on
the theory underpinning the beamforming effect of single and double-layer PRSs in a leaky-wave antenna configuration and subsequently on novel leaky-wave antenna designs. [Continues.]
