摘要： An adjustment method for an antenna device including an antenna, an adjustment circuit including first and second circuits connected in series with the antenna and a communication circuit connected with the adjustment circuit includes: determining constants of the first circuit such that at two frequencies, values of first resistance of first impedance as viewed from an output end of the first circuit toward the antenna each are equal to resistance of target impedance, and absolute values of first reactance of the first impedance are different from one another; and determining constants of the second circuit such that at the frequencies, while values of second resistance of second impedance as viewed from an output end of the adjustment circuit toward the antenna are kept at the values of the first resistance, values of second reactance of the second impedance each are a complex conjugate with reactance of the target impedance.

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： A radiating system of a wireless device transmits and receives electromagnetic wave signals in a frequency region and comprises an external port, a radiating structure, and a radiofrequency system. The radiating structure includes: a ground plane layer with a connection point; a radiation booster with a connection point and being smaller than 1/30 of a free-space wavelength corresponding to a lowest frequency of the frequency region; and an internal port between the radiation booster connection point and the ground plane layer connection point. The radiofrequency system includes: a first port connected to the radiating structure's internal port; and a second port connected to the external port. An input impedance at radiating structure's disconnected internal port has a non-zero imaginary part across the frequency region. The radiofrequency system modifies impedance of the radiating structure to provide impedance matching to the radiating system within the frequency region at the external port.
