Abstract: A device includes a display and a housing. The housing surrounds the display and has four corners defining portions of an exterior surface of the device. The housing includes a first housing segment defining at least part of a first corner of the four corners and configured to operate as an antenna; a second housing segment defining at least part of a second corner of the four corners; and a third housing segment defining at least part of a third corner of the four corners. The third corner forms part of the housing diagonally opposite the second corner. The housing further includes a non-conductive housing component that structurally couples the first housing segment to another portion of the housing.

Abstract: An electronic device may be provided with an antenna having a resonating element and a light source module mounted to a flexible printed circuit and a metal cowling. The module may emit light through a rear housing wall. The printed circuit may be interposed between the metal cowling and a conductive support plate in the rear housing wall. The printed circuit may include a ground trace coupled to the resonating element. A dimpled pad may couple the ground trace to the support plate. Compressive foam may be used to exert a force against the flexible printed circuit that presses the dimpled pad against the conductive support plate. The ground trace and the dimpled pad may form a return path to ground for the resonating element. The dimpled pad may occupy less height within the device than other structures such as metal springs.

Abstract: Aspects of the subject technology relate to electronic devices having microphones. An electronic device may include a microphone and a resonator for the microphone. The resonator may be formed in a device structure that is spatially separated from the microphone. The resonator may be formed in an interior wall of a housing of the electronic device, or in a support structure within an enclosure of the electronic device. A resonator and/or one or more damping features, may reduce a resonance effect, on the microphone, of a resonant cavity within the enclosure of the electronic device and adjacent the microphone.

Abstract: Dielectric such as polyether ether ketone may be used in forming radio-frequency flexible printed circuits. Filler may be incorporated into the dielectric to adjust the coefficient of thermal expansion of the flexible printed circuit. One or more layers of the flexible printed circuit may be unfilled and one or more layers of the flexible printed circuit may be filled. Antennas may be formed from metal traces on the flexible printed circuit, metal electronic device housing structures, or other conductive structures. A transmission line on the flexible printed circuit may couple radio-frequency transceiver circuitry in an electronic device to an antenna. A flexible printed circuit may have a portion with enhanced bendability in a location that overlaps a bend region. The enhanced bendability region may have less filler than other portions of the flexible printed circuit.
