Abstract

A finite element time-domain analysis is performed on a 2-D model of an E-sectoral fan beam horn antenna. The antenna is designed to generate a cylindrical wave over a wide frequency band. A wideband RF pulse is used to analyze the transient response of the antenna, and the results are transformed to recover the frequency response. Open boundary elements are used in the transient analysis to provide an absorbing boundary condition (ABC) at the aperture, and their performance is studied. Good agreement is demonstrated between direct frequency analysis and the transformed time-domain results.<>
