Abstract
A digital video broadcast satellite (DVB-S) television antenna horn assembly, reflector antenna, and a satellite communication system in which the antenna horn includes a suspended dielectric tuning vane that reduces the horn size, modifies the shape the reception pattern, and improves the antenna performance in a number of ways. The antenna horn and the dielectric tuning vane are configured to impart a combined differential phase shift protocol, such as CP polarization, on a circular polarity (CP) signal as the CP signal propagates through the horn from a reception aperture to an output aperture. The dielectric tuning vane may be built into the antenna horn, snap into the antenna horn, be built into a protective plastic lens cover that fits over horn opening, or designed to snap into the plastic lens cover. Various dielectric tuning vanes are suitable for single horn structures and multi-horn structures built into LNB amplifiers.
