Abstract	We present simple and accurate analysis techniques to simulate and design high-gain Fabry-Perot resonant leaky-wave antennas (LWA). To control the radiation properties of these antennas, two metallodielectric periodic structures are used, one acting as a partially reflective surface (PRS) and a second acting as a high impedance surface (HIS). Full-wave method of moments (MoM) is employed for the estimation of the near fields within the LWA. Invoking reciprocity, this allows for a fast estimation of the radiation patterns. Moreover, a simple transverse equivalent network (TEN) is employed from which the leaky-mode complex propagation constant is obtained. Numerical results are presented to demonstrate the capabilities of these techniques.
