    摘要： Disclosed herein are techniques, systems, and methods relating to minimizing mutual coupling between a first antenna and a second antenna. In one implementation, a plurality of antennas and at least one tuning module are provided. A control module may be coupled to the tuning module. The control module may be configured to control the at least one tuning module to alter a phase and an amplitude of a control signal communicated to at least one of the plurality of antennas to reduce mutual coupling between the plurality of antennas.

    摘要： The disclosed invention relates to an antenna configuration that is configured to tune the frequency of transmission without using filters. The antenna configuration comprises a tunable multi-feed antenna configured to wirelessly transmit electromagnetic radiation. A signal generator is configured to generate a plurality of signals that collectively correspond to a signal to be transmitted. The plurality of signals have a phase shift or amplitude difference therebetween. The plurality of signals are provided to a plurality of antenna feeds connected to different spatial locations of the tunable multi-feed antenna. The values of the phase shift and/or amplitude difference define an antenna reflection coefficient that controls the frequency characteristics that the tunable multi-feed antenna operates at, such that by varying the phase shift and or amplitude difference, the frequency characteristics can be selectively adjusted.

    摘要： The disclosed invention relates to a transceiver system having one or more receive antennas that receive a first radio frequency (RF) signal and a plurality of transmit antennas that wirelessly transmit a second RF signal. A local channel determination unit provides data corresponding to the environment of local communication channels (i.e., the communication channels between the transmit antennas and the receive antennas) to a beamforming element, which enables beamforming functionality within the transmit and/or receive antennas (e.g., by using analog or digital weights to vary the radiation pattern generated by the transmit antennas) so as to attenuate RF signals extending between the transmit antennas and the receive antennas. By attenuating signals extending between the transmit and the receive antennas, a high degree of isolation is achieved between transmission and reception paths

    摘要： The present disclosure relates to a wireless communication system configured to transforming the radiating mechanism of the antenna system in such a way to support different operating modes depending on the needs. In some examples, the wireless communication system comprises an antenna structure connected to a signal process unit. The antenna structure comprises a radiating mechanism configured to transmit or receive electromagnetic radiation. A switchable operating mode element is configured to receive a signal and to dynamically vary a quality factor of the radiating element by selectively routing the signal along one of a plurality of signal paths, which respectively provide different antenna parameters to the radiating mechanism, based upon a current operating mode of the wireless communication system. By dynamically varying a quality factor of the radiating element, the wireless communication system can effectively support different operating modes.
