Abstract :
This work presents a formulation for shaping the main reflector of a dual reflector antenna designed to offer an omnidirectional coverage with an arbitrary radiation pattern in the vertical plane. The subreflector is generated by an axis-displaced ellipse and the main reflector is shaped to achieve a prescribed far-field radiation pattern. The shaping procedure is based on geometrical optics (GO) principles. The GO shaping results are validated by analysis provided by the accurate method of moments technique.
