摘要： Various antenna systems are presented that have independently steerable receive and transmit beams. The antenna system may include multiple antenna element systems. Each antenna element system may include multiple phase shifters that alter the phase of received signals and signals to be transmitted. Directions of a first transmit beam, a second transmit beam, a first receive beam, and a second receive beam may be steered independently using the phase shifters. Each antenna element system may include a polarization system.

摘要： An antenna system comprises an antenna feed support and a driver. The antenna feed support is configured to mount a circularly polarized antenna feed to an antenna dish to extend outward along a longitudinal axis of the circularly polarized antenna feed with respect to a reflective surface of the antenna dish. The driver is configured to rotate the circularly polarized antenna feed to adjust alignment between the circularly polarized antenna feed and a remote antenna. The driver can rotate the circularly polarized antenna feed mechanically, electrically or both to adjust alignment between the circularly polarized antenna feed and a remote antenna to reduce cross-pol discrimination at the circularly polarized antenna feed.

摘要： Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for producing meander-line polarizers. In some implementations, a meander-line polarizer includes a dielectric substrate made of a polyester polymer material and meander-line arrays formed on a surface of the dielectric substrate. Each meander-line array includes a sequence of alternating perpendicular conductive traces that are formed the surface of the dielectric substrate by applying conductive ink to the surface of the dielectric substrate using a template that defines a location and dimensions of each conductive trace of each meander-line array.

摘要： Systems and methods are provided for separating the uplink signal from the downlink signal in a satellite communication system. A communication terminal for satellite communications is provided, comprising a reflector having a prime focus; a first feed located at the prime focus of the reflector and in optical communication with the reflector; a frequency-selective surface module having a reflected focus and located at a point along a communication path between the main reflector and the first feed; and a second feed located at the reflected focus of the frequency-selective surface module and in optical communication with the frequency-selective surface module.

摘要： An apparatus and method for continuously shifting the phase of an input signal includes a quadrature hybrid having an input/output port for receiving an input radio frequency (RF) signal and outputting a phase shifted RF signal. An analog shifting unit is connected to the quadrature hybrid for performing an intermediate phase shift on the input RF signal. An additional analog shifting unit is connected to an isolation port of the quadrature hybrid to receive an intermediate output signal based on the intermediate phase shift, and shifting a phase of the intermediate output signal to produce an intermediate input signal. The analog shifting unit performs a final phase shift of the intermediate input signal and the final phase shifted intermediate input signal is output, at the input/output port, as the phase shifted RF signal.

摘要： An apparatus and method for mitigating polarization mismatch in reflector antenna systems. A feed unit is configured to determine a polarization mismatch between a first polarization associated with a first wave and a second polarization associated with a reflector unit. The feed unit pre-distorts the first wave to achieve a compensated polarization for reducing and/or eliminating a polarization mismatch. The pre-distorted first wave having the compensated polarization is used to illuminate the reflector unit. A re-radiated wave is reflected by the reflector unit. Furthermore, the level of the re-radiated wave is increased as a result of the pre-distortion.
