Analysis of a monopole mounted near or at the edge of a half-plane

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. Results are presented for input impedance of a monopole versus distance from the half-plane edge and versus angle for an edge-mounted antenna, Simple expressions for the surface current density induced on the half-plane are derived, and an attachment mode is constructed 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. Results obtained from the MM/GTD method are also presented for comparison.
