Abstract
An antenna method and apparatus includes a slot antenna configured within a ground plane and a conductive reflector backing the slot antenna and configured to reflect RF energy. The slot antenna, ground plane, and the reflector cooperatively form a reflector-backed slot antenna and a radial-mode waveguide providing an inverse, mirrored, substantially cosecant-squared radiation pattern.
