Claim Text:
1. An antenna comprising; a divided wave guide comprising a plurality of individual wave guides having respective wave guide widths for propagation of respective individual signals in an operating frequency band, the divided wave guide having a divided port comprising ports of the plurality of individual wave guides; a common wave guide horn coupled with the divided waveguide and comprising a plurality of sections between a first end of the common wave guide horn adjacent to the divided port of the divided wave guide and a second end at an outer aperture of the common wave guide horn, the plurality of sections of the common wave guide horn having increasing wave guide cross-sectional size at each geometry transition from the first end to the second end and converting between the individual signals in the plurality of individual wave guides and a composite signal in the common wave guide horn; and a circuit connectively coupled with the plurality of individual wave guides, the circuit comprising a first set of junctions that output a first set of summation signals and a first set of delta signals from the individual signals, and a second set of junctions that output an elevation error tracking signal and an azimuth error tracking signal from the first set of summation signals and the first set of delta signals.
