Abstract: A reconfigurable beam-forming network for use with a transmitter has a waveguide R-switch that is interconnected with a Magic T. The R-switch contains phasing elements and is connected to a dual-mode power-­dividing network, which in turn is connected to first, second and third region power-dividing networks, each having their own feed horn array. The R-switch can be moved to three different positions so that in a first position power is divided between two input ports of the dual-mode network on substantially a fifty-fifty basis with the power on the two input ports being out of phase on a positive basis. In a second position of the R-switch, power is also divided on substantially a fifty-fifty basis between the two input ports but the power is out of phase between the two ports on a negative basis. In a third position of the R-switch, substantially all of the power entering the R-switch is passed into the first input port of the dual-mode network. The power being fed to the feed horns of any one of the regions has the same phase. In a variation of the invention, the R-switch and Magic T are replaced by a variable phase shifter and Magic T.
