FDTD Analysis of a New Leaky Traveling Wave Antenna

Abstract

A new antenna is proposed based on a structure first constructed by Menzel that utilizes the leaky wave phenomena of the first higher order mode. This work seeks to determine the effect on performance of the antenna due to varying geometries. Standard antenna range far-field and near-field measurements are not sensitive enough to extract the propagation constant. A numerical simulation was thus developed using the Finite Difference Time Domain (FDTD) method to extract the propagation constant. The simulation was validated with published analytical data as well as measured data.
