ABSTRACT:
The present invention provides a bifocal reflector antenna with no aberration and a configuration process thereof wherein the two-dimensional Ray Lattice Method is extended to the three-dimensional method. By setting the central section curve of a subreflector or main reflector as an initial condition, the surface curves of the sub- and main reflectors are determined so that a ray from the focus to the antenna aperture can satisfy the reflection law and path length condition. The aberration over the antenna aperture is perfectly eliminated by using the new method.
