  • Patent number: 11605897
    Abstract: A communication device is made with a metallic frame having an interior mounting surface for receiving one or more functional components. The metallic frame includes a first frame member having a first portion extending uninterrupted across one lateral side of the metallic frame. The first portion provides structural support to the communication device. A T-shaped slot antenna is formed in a second portion of the first frame member adjacent to the first portion. The T-shaped slot antenna has first and second arms separated at a gap and partially encompassing a slot. The second portion of the first frame member enables radio frequency communication by at least one of the functional components via the T-shaped slot antenna of the communication device.

  • Publication number: 20230076710
    Abstract: An antenna for receiving wireless power from a transmitter is provided. The antenna includes multiple antenna elements, coupled to an electronic device, configured to receive radio-frequency (RF) power waves from the transmitter, each antenna element being adjacent to at least one other antenna element. Furthermore, the multiple antenna elements are arranged so that an efficiency of reception of the RF power waves by the antenna elements remains above a predetermined threshold efficiency when a human hand is in contact with the electronic device, the predetermined threshold efficiency being at least 50%. Lastly, at least one antenna element is coupled to conversion circuitry, which is configured to (i) convert energy from the received RF power waves into usable power and (ii) provide the usable power to the electronic device for powering or charging of the electronic device.

  • Patent number: 11356235
    Abstract: An analog self-interference cancellation technique for In-Band Full-Duplex (IBFD) systems generates an inherent secondary self-interference (SI) signal of a circulator and uses that signal to cancel a primary SI signal leaked from a transmitter port within a communication device. The communication device manipulates the phase and angle of this secondary SI, using an adjustable Impedance Mismatch Terminal (IMT) circuit. The result is an efficient SI cancellation technique in the analog domain, which uses the circulator inherent SI signals.

  • Patent number: 11172060
    Abstract: A communication device, method and computer program product enable improved communication performance by switching or tuning antennas based on detecting touches on edge display(s) of the communication device that has at least one antenna positioned along edges of a housing assembly. A controller monitors edge display(s) of the communication device to determine portions of the edge display(s) that are touched and associates the at least one antenna that is proximate to the portions of the edge display(s) that are touched The controller configures a radio frequency front end of the communication device to switch or tune the at least one antenna in order to provide at least one of: mitigating detrimental effects to antenna performance by the at least one antenna or remaining within regulatory limits for RF transmission exposure.
