Patent number: 9781612Abstract: Representative implementations of devices and techniques provide self-interference suppression for a transceiver of a wireless communication system. To minimize interference from a transmit signal appearing on a receive path of the system, a cross-correlation is minimized between the transmit signal and a desired receive signal.Type: GrantFiled: March 31, 2014Date of Patent: October 3, 2017Assignee: Intel IP CorporationInventors: Emil Buskgaard, Elpiniki Tsakalaki, Osama Nafeth Alrabadi, Mikael Bergholz Knudsen, Gert Pedersen, Alexandru Daniel Tatomirescu, Poul Olesen, Peter Bundgaard, Pevand Bahramzy

Patent number: 9570796Abstract: An antenna having a plurality of ports coupled to at least one radiator opening or protuberance formed on a metallic surface. A plurality of modulators are coupled to the plurality of respective ports and configured to modulate phase or amplitude of a plurality of signals radiated at the plurality of respective ports. A combiner is configured to combine the modulated signals to substantially cancel power reflected from the plurality of respective ports, wherein the plurality of respective ports are functionally aggregated into a single port.Type: GrantFiled: October 28, 2013Date of Patent: February 14, 2017Assignee: Intel IP CorporationInventors: Osama Nafeth Alrabadi, Alexandru Daniel Tatomirescu, Mikael Bergholz Knudsen, Gert F.

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.

Patent number: 8805300Abstract: The disclosed invention relates to a MIMO (multiple input, multiple output) wideband transceiver. In some cases, the MIMO wideband transceiver comprises a signal processor that outputs or receives a plurality of distinguishable data streams. A first data stream is provided to a first antenna port connected to a plurality of wideband antennas, while a second data stream is provided to a second antenna port connected to a wideband antenna. A spatial filter element configured to assign antenna weights to the plurality of wideband antennas, which cause the wideband antennas to operate in a manner that attenuates wireless signals, at a frequency range at which the wideband transmit wideband radiate, in the direction of the wideband antenna without attenuating the wireless signals in other directions. By attenuating signals extending between the plurality of wideband antennas and the wideband antenna, wideband decoupling between first and second antenna ports is achieved.Type: GrantFiled: August 30, 2012Date of Patent: August 12, 2014Assignee: Intel Mobile Communications GmbHInventors: Osama Nafeth Alrabadi, Mikael Bergholz Knudsen, Gert F.
