ANTENNA SYSTEM FOR BROADBAND SATELLITE COMMUNICATION IN THE GHz FREQUENCY RANGE, COMPRISING HORN ANTENNAS WITH GEOMETRICAL CONSTRICTIONS

摘要

An antenna system for wireless communication of data includes at least four horn antennas. Each horn antenna is configured to support communications at two mutually orthogonal linear polarizations. Each horn antenna includes an inner wall enclosing a space and geometric constrictions each protruding inwardly from the inner wall into the space along a corresponding polarization plane of one of the two linear polarizations. At least one of the inner wall or the geometric constrictions has a stepped structure.
