The present disclosure relates to an antenna system for wireless communication of data. In one implementation, the system includes at least four horn antennas. Each horn antenna may have a three-layered cavity, and each layer may be filled with dielectric. The system may further include two microstrip line networks. The microstrip networks may be between two adjacent layered portions and configured to communicate with the horn antennas.

Antenna system for broadband satellite communication in the GHz frequency range, comprising dielectrically filled horn antennas

An antenna system for wireless communication of data includes at least two antenna modules constructed from a plurality of electrically-conductive layers and a first waveguide network configured to communicate data with the at least two antenna modules. Each antenna module includes at least two radiating elements. Each radiating element is configured to support communications at a first polarization and a second polarization that are orthogonal to one another. Each antenna module also includes a first microstrip line network configured to communicate with the at least two radiating elements at the first polarization and a second microstrip line network configured to communicate with the at least two radiating elements at the second polarization. At least one of the electrically-conductive layers is located between the first and second microstrip line networks.

Antenna system for broadband satellite communication in the GHz frequency range, comprising a feeding arrangement

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.
