摘要： Methods and systems are described for providing end-to-end beamforming. For example, end-to-end beamforming systems include end-to-end relays and ground networks to provide communications to user terminals located in user beam coverage areas. The ground segment can include geographically distributed access nodes and a central processing system. Return uplink signals, transmitted from the user terminals, have multipath induced by a plurality of receive/transmit signal paths in the end to end relay and are relayed to the ground network. The ground network, using beamformers, recovers user data streams transmitted by the user terminals from return downlink signals. The ground network, using beamformers generates forward uplink signals from appropriately weighted combinations of user data streams that, after relay by the end-end-end relay, produce forward downlink signals that combine to form user beams.

摘要： Ultrawideband (UWB) beamforming networks are provided. A UWB beamforming network can have azimuth angle scanning and elevation angle scanning. A modified version of the Blass matrix topology can be used to achieve two-dimensional (2D) scanning behavior. The beamforming network can simultaneously excite a plurality of beams, and each of these beams can be at any chosen frequency inside the bandwidth that the beamformer covers. Each beam can be designed to point at any arbitrary direction, which can be defined by the desired elevation angle and azimuth angle, in the 2D plane.

摘要： Systems and methods relating to multi-beam forming networks using an antenna array. A matrix circuit for feeding elements of an antenna array to produce multiple beams is provided. To address beam squint issues, beam squint is mitigated by using a series of phase shifters with specific phase-delay performances between the matrix circuit and the antenna array elements. A linearly increasing or decreasing phase difference in the signals fed into adjacent antenna array elements across the array mitigates or eliminates beam squint in the resulting multiple beams. The phase shifters are programmed to provide this increasing or decreasing phase differences.
