Constrained Overlapping Feed Arrays for Contiguous Contour Beam Reflector Antennas,
Abstract
Contour beam antennas with contiguous beams generally utilize frequency and/or polarization discrimination between the adjacent beams for isolation purposes. When polarization discrimination is not possible and the frequency separation between channels is small, isolation between the adjacent beam feed ports can be achieved with a -3 dB loss in the overlapping feeds. An alternative to this approach, with less loss (approx. 0.5 dB), may be achieved by 'constraining' overlapping feed radiating elements which serve both contiguous beams.
