Patent number: 11784388Abstract: An electronic device is described. This electronic device includes: an interface circuit; and an antenna having a radiator and multiple pairs of reflectors arranged along different axes passing through the radiator in a horizontal plane. A given pair of reflectors includes reflectors on opposite sides of the radiator and along a given axis. During operation, the interface circuit provides control signals to switching elements that selectively electrically couple one or more of the reflectors in the pairs of reflectors to ground, where the one or more of the reflectors modify an antenna radiation pattern of the radiator. Then, the interface circuit communicates, via the antenna, a packet or a frame with a second electronic device, where the communication involves transmitting or receiving wireless signals corresponding to the packet or the frame.Type: GrantFiled: March 23, 2021Date of Patent: October 10, 2023Assignee: ARRIS Enterprise LLCInventors: Khaled A. Obeidat, Douglas Blake Kough

Patent number: 11631942Abstract: An electronic device includes: a first pair of antennas having a first polarization along a first direction in a plane, where the first pair of antennas are spatially offset from each other along a second direction in the plane; and a second pair of antennas having a second polarization along the second direction, where the second pair of antennas are spatially offset from each other along the first direction. During operation, the electronic device may configure switching elements to: select the first pair of antennas and electrically couple the second pair of antennas to ground; or select the second pair of antennas and electrically couple the first pair of antennas to ground.

Publication number: 20220393755Abstract: An electronic device that uses an arbitrary transmit polarization is described. This electronic device includes: a first antenna having a first predefined polarization; and a second antenna having a second predefined polarization, where the second predefined polarization is different from the first predefined polarization. During operation, an interface circuit in the electronic device selectively transmits, from the first antenna, first wireless signals corresponding to the packet or the frame. Moreover, the interface circuit selectively transmits, from the second antenna, second wireless signals corresponding to the packet or the frame, where the second wireless signals have a same magnitude as the first wireless signals, and the second wireless signals are transmitted from the second antenna concurrently (or at the same time) as the first wireless signals are transmitted from the first antenna. Note that the interface circuit may dynamically modify the transmit polarization during the communication.Type: ApplicationFiled: August 17, 2022Publication date: December 8, 2022Inventors: Douglas Blake Kough, Khaled A.

Patent number: 11515642Abstract: An electronic device that communicates a packet or a frame is described. This electronic device includes: at least an antenna having an antenna radiation pattern; an interface circuit; and an antenna cover that includes an integrated static lens, where the antenna cover is selected from a set of antenna covers that includes different integrated static lenses. During operation, the interface circuit may transmit, from the antenna, wireless signals corresponding to the packet or the frame, where the integrated static lens modifies the antenna radiation pattern of the antenna. For example, the integrated static lens may cause the wireless signals to converge or diverge. Alternatively, the integrated static lens may change an angular elevation of the antenna radiation pattern and/or may provide a correction for pathloss as a function of angle. Note that the integrated static lens may be a stepwise approximation to a predefined function.Type: GrantFiled: March 16, 2021Date of Patent: November 29, 2022Assignee: ARRIS Enterprises LLCInventors: Rajesh Koganti, Douglas Blake Kough

Patent number: 9531071Abstract: Electronic devices may include radio-frequency transceiver circuitry and antenna structures. The antenna structures may include antenna resonating elements such as dual-band antenna resonating elements that resonate in first and second communications bands. The antenna structures may also contain parasitic antenna elements such as elements that are operative in only the first or second communications band and elements that are operative in both the first and second communications bands. The antenna resonating elements and parasitic elements may be mounted on a common dielectric carrier. The dielectric carrier may be mounted within a slot or other opening in a conductive element. The conductive element may be formed from conductive housing structures in an electronic device such as a portable computer. The portable computer may have a clutch barrel with a dielectric cover. The dielectric cover may overlap and cover the slot and the dielectric carrier.Type: GrantFiled: January 11, 2016Date of Patent: December 27, 2016Assignee: Apple Inc.Inventors: Jerzy S.
