The present invention discloses a method for generating multiple antenna beams and a system for generating multiple antenna beams. The system comprises a first reflector surface that has a primary and at least a first auxiliary surface, and a second reflector surface, and also comprises first, second, and third feed horns. The first feed horn illuminates the primary surface with radio frequency (RF) energy, the second feed horn illuminates the auxiliary surface with RF energy, and the third feed horn illuminates the second reflector surface with RF energy. The first feed horn and third feed horn are removed from an axis of symmetry of the first auxiliary surface. The method comprises illuminating a primary portion of a first reflector surface with radio frequency (RF) energy from a first feed horn, illuminating an auxiliary portion of the first reflector surface with RF energy from a second feed horn, illuminating a second reflector surface with RF energy from a third feed horn, wherein the first feed horn and third feed horn are removed from an axis of symmetry of the auxiliary portion of the first reflector surface.

A waveguide switch matrix is disclosed. The switch matrix includes a number of input waveguides that may be selectably connected to a number of output waveguides. A switch apparatus is provided at the intersection of each input waveguide and each output waveguide. The switch apparatus includes probes inserted into both the input waveguide and the output waveguide. The probes are connected through a switch arrangement. When a particular input waveguide is to be coupled to a particular output waveguide, the switch arrangement between the probes of the waveguides is closed to provide a signal path for the electromagnetic energy.

A coaxial "M" switch having three coaxial input connectors (A, B, C) spaced evenly from each other, and three coaxial output connectors (1, 2, 3) identically arranged. In a cylindrical barrel embodiment (10) the input and output connectors are located at opposite ends of a cylindrical configuration. In one planar embodiment (30), the input and output connectors alternate with each other and define a hexagonal configuration (40). In another planar embodiment, the input connectors (A, B, C) define an inner triangular configuration (70) that is surrounded by the output connectors (1, 2, 3) defining an outer triangular configuration. In each embodiment, reeds are actuated in predetermined configurations to define three switch positions.
