Patent number: 10763566Abstract: An electronic device may include a millimeter wave transceiver, a first antenna having a first resonating element at a first side of a substrate, and a second antenna having a second resonating element at a second side of the substrate. A first coplanar waveguide may convey millimeter wave signals between the transceiver and the first resonating element and a second coplanar waveguide may convey millimeter wave signals between the transceiver and the second resonating element. The first coplanar waveguide may be coupled to the first resonating element through the second coplanar waveguide. The second coplanar waveguide may be coupled to the second resonating element through the first coplanar waveguide. Ground conductors in the coplanar waveguides may form antenna ground planes for the first and second antennas while serving to maximize electromagnetic decoupling between the coplanar waveguides and thus isolation between the ports of the transceiver.Type: GrantFiled: July 20, 2017Date of Patent: September 1, 2020Assignee: Apple Inc.Inventors: Basim H. Noori, Matthew A. Mow, Simone Paulotto, Khan M. Salam

Patent number: 10476136Abstract: An electronic device may be provided with wireless circuitry, a conductive housing, and a display. The display may have an active area that displays image data and an inactive area that does not display image data. The active area may completely surround the inactive area at a front face of the device. A speaker port may be aligned with the inactive area and may emit sound through the inactive area. The wireless circuitry may include first and second antenna arrays. The first array may be configured to transmit and receive wireless signals at frequencies between 10 GHz and 300 GHz through the inactive area of the display. The second array may be configured to transmit and receive wireless signals at frequencies between 10 GHz and 300 GHz through a slot in a rear wall of the conductive housing. Control circuitry may perform beam steering using the first and second arrays.Type: GrantFiled: July 20, 2017Date of Patent: November 12, 2019Assignee: Apple Inc.Inventors: Matthew A. Mow, Basim H.

Patent number: 10263340Abstract: An electronic device may be provided with wireless circuitry. The wireless circuitry may include one or more dual-frequency dual-polarization patch antennas. Each patch antenna may have a patch antenna resonating element that lies in a plane and a ground that lies in a different parallel plane. The patch antenna resonating element may have a first feed located along a first central axis and a second feed located along a second central axis that is perpendicular to the first central axis. The patch antenna resonating element may be rectangular, may be oval, or may have other shapes. A shorting pin may be located at an intersecting point between the first and second axes. The patch antennas may be used in beam steering arrays. The patch antennas may be used for wireless power transfer at microwave frequencies or other frequencies and may be used to support millimeter wave communications.Type: GrantFiled: December 20, 2017Date of Patent: April 16, 2019Assignee: Apple Inc.Inventors: Basim H.

Patent number: 6624695Abstract: High efficiency DC to RF conversion with use of active harmonic insertion is provided for power amplification over a wide dynamic range of input signal level. Specifically, a power amplifier device including at least a final amplification stage is operated to receive an input signal of a fundamental frequency. A drive signal is produced which includes a fundamental signal component of the fundamental frequency and at least one harmonic signal component of a harmonic frequency that is substantially an integer multiple of the fundamental frequency, wherein relative phase shift and relative amplitude of the components are controlled over at least an order of magnitude of dynamic range of the input signal. As the signal level of the input signal decreases (or increases), the desired proportion of signal levels is maintained between the components.Type: GrantFiled: October 31, 2001Date of Patent: September 23, 2003Assignee: Tropian, Inc.Inventors: John Sevic, Khan M.
