A simple transmission line approach for the rapid analysis of multiple fed Leaky Wave antennas based on Fabry-Perot cavities is presented. The method is based on the superposition of the travelling leaky waves excited by each of the applied source. The propagation constant of the leaky waves inside the Fabry-Perot cavity is computed the Transverse Resonance Technique (TRM). The procedure is completely analytic since the antenna does not require a superstrate composed by unconventional FSS elements. This antenna configuration allows the synthesis of very high gain antennas while preserving reasonable bandwidth.

Abstract
A simple transmission line approach for the rapid analysis of multiple fed Leaky Wave antennas based on Fabry-Perot cavities is presented. The method is based on the superposition of the travelling leaky waves excited by each of the applied source. The propagation constant of the leaky waves inside the Fabry-Perot cavity is computed the Transverse Resonance Technique (TRM). The procedure is completely analytic since the antenna does not require a superstrate composed by unconventional FSS elements. This antenna configuration allows the synthesis of very high gain antennas while preserving reasonable bandwidth.File in questo prodotto:
