Patent number: 10895634Abstract: An electronic device such as a wristwatch may be provided with a phased antenna array for conveying first signals at a first frequency between 10 GHz and 300 GHz and a non-millimeter wave antenna for conveying second signals at a second frequency below 10 GHz. The device may include conductive housing sidewalls and a display. Conductive structures in the display and the conductive housing sidewalls may define a slot element in the non-millimeter wave antenna. The phased antenna array may be mounted within the slot element, aligned with a spatial filter in the display, or aligned with a dielectric window in the conductive housing sidewalls. Control circuitry may process signals transmitted by the phased antenna array and a reflected version of the transmitted signals that has been received by the phased antenna array to detect a range between the device and an external object.Type: GrantFiled: February 21, 2018Date of Patent: January 19, 2021Assignee: Apple Inc.Inventors: Jayesh Nath, Simone Paulotto, Mario Martinis, Eduardo Jorge Da Costa Bras Lima, Andrea Ruaro, Carlo Di Nallo, Matthew A.

Patent number: 10879606Abstract: An electronic device such as a wristwatch may have a housing with metal sidewalls and a display having conductive display structures. Printed circuits having corresponding ground traces may be coupled to the display for conveying data to and/or from the display. The conductive display structures may be separated from the metal sidewalls by a gap. A conductive interconnect may be coupled to the metal sidewalls and may extend across the gap to the conductive display structures. The conductive interconnect may be coupled to the ground traces on the printed circuits and/or may be shorted or capacitively coupled to the conductive display structures. When configured in this way, the metal sidewalls, the conductive display structures, and the conductive interconnect may define the edges of a slot antenna resonating element for a slot antenna.Type: GrantFiled: April 21, 2020Date of Patent: December 29, 2020Assignee: Apple Inc.Inventors: Andrea Ruaro, Carlo Di Nallo, Eduardo Jorge Da Costa Bras Lima, Jayesh Nath, Mario Martinis, Mattia Pascolini, Zheyu Wang, Sameer Pandya

Patent number: 10868356Abstract: An electronic device may include an antenna element, coil, sensor board, and grounding ring structures. The coil may receive wireless charging signals through the grounding ring structures. The grounding ring structures may include concentric ring-shaped traces separated by at least one gap. The ring-shaped traces and gaps may configure the grounding ring structures to short antenna currents at relatively high frequencies from the antenna element to a ground trace on the sensor board while blocking currents at relatively low frequencies. The grounding ring structures may include conductive wings that increase capacitive coupling between the grounding ring structures and the antenna element. The grounding ring structures may be soldered to the antenna element. The antenna element and the grounding ring structures may be formed from traces patterned on the same substrate. The ground trace may form part of an antenna without substantially impairing wireless charging efficiency of the coil.Type: GrantFiled: September 6, 2019Date of Patent: December 15, 2020Assignee: Apple Inc.Inventors: Eduardo Jorge Da Costa Bras Lima, Andrea Ruaro, Dimitrios Papantonis, Jayesh Nath, Jiaxiao Niu, Mario Martinis, Mattia Pascolini, Michael R.

Patent number: 10484112Abstract: An electronic device such as a wristwatch may include a housing with a dielectric rear wall. Wireless circuitry in the device may include an antenna formed on or over the rear wall. Matching circuitry may match the impedance of the antenna to the rest of the wireless circuitry. Processing circuitry may gather receive signal strength information and/or phase and magnitude information from radio-frequency signals received through the rear wall. The processing circuitry may track the position of the device and accumulate user statistics over time. The processing circuitry may determine whether changes in loading of the antenna through the dielectric rear housing wall have occurred based on the receive signal strength information, user statistics, and/or phase and magnitude information. If a change is detected, the processing circuitry may adjust the matching circuitry to mitigate any potential antenna detuning as a result of the change.Type: GrantFiled: February 24, 2017Date of Patent: November 19, 2019Assignee: Apple Inc.Inventors: Mattia Pascolini, Eduardo Jorge da Costa Bras Lima, Carlo Di Nallo, Andrea Ruaro, Mario Martinis, Zheyu Wang, Jayesh Nath
