Conference paper

This paper presents a numerical investigation of the electromagnetic properties of the backfire monofilar helical antenna. The current distribution along the helical conductor, the input impedance, and the front-to-back ratio are calculated and analyzed for the backfire operation of the antenna. A parametric study of the helical geometry and the resulting antenna characteristics will be described and discussed.

The currents and fields are calculated using the simulation software AWAS based on the Method of Moments with a wire representation of the ground plane.
