Patent number: 9793983Abstract: Examples of a system and method for adaptively tuning a radio frequency (RF) front-end are generally described herein. In some examples, the frequency of a transmit signal of RF front-end circuitry is swept in at least a part of the RF transmit band. RF power in a receiver is detected as a function of the RF frequency of the transmit signal to determine a location of at least one tunable notch or other band stop element in the frequency domain. Information from the detected RF power is determined as a function of the RF frequency of the transmit signal. The RF front-end circuitry is adjusted to a selected frequency response using the determined information.Type: GrantFiled: June 23, 2016Date of Patent: October 17, 2017Assignee: Intel IP CorporationInventors: Poul Olesen, Peter Bundgaard, Mikael Bergholz Knudsen

Patent number: 9252492Abstract: 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.Type: GrantFiled: August 29, 2012Date of Patent: February 2, 2016Assignee: Intel Deutschland GmbHInventors: Osama Nafeth Alrabadi, Alexandru Daniel Tatomirescu, Mikael Bergholz Knudsen, Gert F.

Patent number: 9225381Abstract: 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.Type: GrantFiled: March 11, 2013Date of Patent: December 29, 2015Assignee: Intel Deutschland GmbHInventors: Mauro Pelosi, Alexandru Daniel Tatomirescu, Mikael Bergholz Knudsen, Gert F.

Patent number: 8874047Abstract: 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.Type: GrantFiled: March 19, 2012Date of Patent: October 28, 2014Assignee: Intel Mobile Communications GmbHInventors: Osama Nafeth Alrabadi, Mikael Bergholz Knudsen, Gert F.
