N2 - Highly directive beams can be produced using Fabry-Pérot cavity Leaky-Wave antennas (LWA). These antennas have been typically implemented using a periodic partially-reflecting surface (PRS) forming a half-wavelength resonant cavity with a ground plane [1-3]. More recently, a planar artificial magnetic conductor (AMC) ground plane has been proposed as a means to reduce the profile of such antennas [4]. Although in all cases the cavity resonance increases the directivity of simple radiating sources, the strong directivity results in a very small antenna bandwidth. An efficient analysis technique of half-wavelength periodic 2-D LWAs has been presented based on the principle of reciprocity and full-wave spectral domain analysis [3]. An optical cavity ray model has also been used to find the radiation performance and resonance condition of this type of antennas [1, 2].
