Patent number: 10854953Abstract: An electronic device may include a peripheral conductive housing sidewall with an integral ledge extending towards the device interior. A display cover layer may be supported by the integral ledge. A slot antenna may be formed from a slot in the integral ledge. The integral ledge may be mounted to a surface of a substrate and coupled to a conductive rear housing wall by a conductive layer extending over an additional surface of the substrate. The sidewall may include a vertical portion extending from the ledge to the rear wall. The slot antenna may be fed via near-field coupling using a conductive patch that is located within the slot at the surface of the substrate. The conductive layer, rear housing wall, and vertical portion may form a cavity for the slot antenna. The conductive layer may isolate the slot from interference with a battery, display circuitry, or other components.Type: GrantFiled: September 27, 2017Date of Patent: December 1, 2020Assignee: Apple Inc.Inventors: Pietro Romano, Umar Azad, Harish Rajagopalan, David Garrido Lopez, Lu Zhang, Rodney A.

Patent number: 10741909Abstract: An electronic device may have peripheral conductive structures and a conductive layer that define edges of a slot element for a slot antenna. The slot element may be configured to cover wireless communications in a 1575 MHz satellite navigation band and 2.4 GHz and 5 GHz wireless local area network bands. A tuning circuit may be coupled across the slot approximately half way across the length of the slot. The antenna tuning circuit may include an inductor coupled in series with a notch filter (in scenarios where the slot is long enough to cover the 1575 MHz satellite navigation band in its fundamental mode) or may include a capacitor coupled in series with a notch or low pass filter. The fundamental mode and one or more harmonic modes of the slot element may cover the satellite navigation and wireless local area network bands.Type: GrantFiled: September 26, 2017Date of Patent: August 11, 2020Assignee: Apple Inc.Inventors: Harish Rajagopalan, Pietro Romano, Umar Azad, David Garrido Lopez, Lu Zhang, Rodney A.

Patent number: 10490881Abstract: An electronic device may have hybrid antennas that include slot antenna resonating elements formed from slots in a ground plane and planar inverted-F antenna resonating elements. The planar inverted-F antenna resonating elements may each have a planar metal member that overlaps one of the slots. A return path and feed may be coupled in parallel between the planar metal member and the ground plane. Adjustable circuits such as tunable inductors may be used to tune the hybrid antennas. Adjustable circuits may bridge the slots in hybrid antennas and may be included in return paths that are coupled between the planar metal members of the planar inverted-F antenna resonating elements and the ground plane. A slot may be selectively divided to from two slots using switching circuitry.Type: GrantFiled: March 10, 2016Date of Patent: November 26, 2019Assignee: Apple Inc.Inventors: Umar Azad, Harish Rajagopalan, Rodney A.

Patent number: 10290946Abstract: An electronic device may have a hybrid antenna that includes a slot resonating element formed from a slot in a ground plane and a planar resonating element formed over the slot. A parasitic element may be disposed over the planar element. A switch may couple the parasitic element to the ground. A tunable circuit may couple the planar element to the ground. The switch and tunable circuit may be placed in different tuning states. In a first state, the tunable circuit and switch form open circuits. In a second state, the tunable circuit may an open circuit and the switch is closed. In a third state, the tunable circuit forms a return path and the switch forms an open circuit. This may allow the antenna to operate with satisfactory efficiency in low, mid, and high bands despite volume constraints imposed on the antenna.Type: GrantFiled: September 23, 2016Date of Patent: May 14, 2019Assignee: Apple Inc.Inventors: Pietro Romano, Harish Rajagopalan, Umar Azad, Lu Zhang, Rodney A.

Patent number: 10283844Abstract: An electronic device may include a metal housing and a distributed loop antenna. The antenna may include a dielectric carrier. The antenna may include a distributed loop antenna resonating element that extends around the carrier and a loop antenna feed element on the carrier. Portions of the feed element and loop antenna resonating element may be formed from the housing. The feed element may be directly fed and may indirectly feed the distributed loop antenna resonating element via near field electromagnetic coupling. The loop antenna resonating element may include a conductive sheet on the carrier. The conductive sheet and the housing may form a conductive loop path of the loop antenna resonating element. A capacitance may be interposed in the conductive loop path and may be formed by a gap between the conductive sheet and the housing. A speaker driver may be placed within a cavity in the carrier.Type: GrantFiled: September 23, 2016Date of Patent: May 7, 2019Assignee: Apple Inc.Inventors: Harish Rajagopalan, Pietro Romano, Rodney A.

Patent number: 10164679Abstract: An electronic device may have conductive housing structures and first, second, third, and fourth slot antennas having respective first, second, third, and fourth slot elements in the conductive housing structures. The third slot element may be interposed between the first and second slot elements and the second slot element may be interposed between the third and fourth slot elements. Switching circuitry may be coupled between a transceiver and the slot elements. Control circuitry may control the switching circuitry to activate a selected pair of the slot antennas based on an orientation of the device or other data. The active pair of antennas may convey radio-frequency signals at the same frequencies using a multiple-input and multiple-output (MIMO) communications scheme. In this way, the device may perform wireless communications at relatively high data throughputs regardless of how the device is being held by a user.Type: GrantFiled: September 27, 2017Date of Patent: December 25, 2018Assignee: Apple Inc.Inventors: Harish Rajagopalan, Umar Azad, Pietro Romano, David Garrido Lopez, Lu Zhang, Rodney A.
