Abstract
In this paper we study the dispersion properties of broadband 2-D multi-layer Fabry Perot Leaky-Wave antennas (LWA). The structure consists of three layers of periodic metallodielectric Partially Reflective Surfaces (PRS) placed over a ground plane forming three air cavities of about half wavelength each. Initially, full wave periodic analysis is employed in commercial simulation software (CST Microwave StudioTM) to estimate the directivity performance through measuring the near field and using reciprocity. A dispersion analysis of the leaky modes of the structure is performed by calculating the complex wavenumber within the first cavity. A dipole source is used for excitation of the cavity modes.
