Abstract :
The finite difference time domain (FD-TD) method has been used to study the short backfire antenna which is a compact feed for reflector antennas. A parametric study of a short backfire antenna has been performed which, for the first time, enables an optimum design to be obtained. The computed results have been validated by constructing and measuring an experimental antenna which gave measured results in good agreement with the predictions
