Analysis of Wire Antennas Mounted Near or at the Edge of a Half-Plane

摘要

The problem of a monopole antenna mounted near or at the edge of a half-plane is solved using a hybrid moment method solution with an integral expression for the exact half-plane Green's function, and by the MM/GTD method. Results are presented for input impedance of a lambda/4 monopole vs. distance from the half-plane edge, and vs. angle for an edge-mounted antenna. Simple expressions for the surface current density induced on the half-plane are derived and used to synthesize an attachment mode for use with the author's previously developed surface patch moment method solution when a wire is attached at or near an edge of a finite plate.
