The plane earth surface influence on the directive pattern of above-ground vertical antenna is considered taking into account the complex dielectric permeability of the surface. Expressions for directive pattern of the system “antenna + underlaying surface" are obtained and analyzed both for antenna phased in directions of incident and reflected waves. Situation and dimensions of the region significant for reflection from the surface are evaluated on the basis of physical optics approach. Simple technique for earth surface complex dielectric permeability estimation is described.
