    Abstract: An electronic device may be provided with a sidewall, a display module separated from the sidewall by a gap, a display cover, a conductive bucket mounted to the display cover within the gap, and a phased antenna array mounted to the bucket for conveying millimeter wave signals through the display cover. The sidewall may form part of an antenna for conveying non-millimeter wave signals. The array may include resonating elements on a substrate. The resonating elements may be fed using feed terminals coupled to alternating sides of the resonating elements. Dielectric layers having a dielectric constant lower than that of the display cover may be provided on a surface of the display cover within the bucket. The array may operate with satisfactory efficiency despite the small amount of available space within the device, electromagnetic interference from the sidewall and the display module, and dielectric loading by the display cover.

    Abstract: An electronic device may be provided with an antenna and transceiver circuitry such as millimeter wave transceiver circuitry. The antenna may include an antenna ground and a resonating element. The resonating element may include a cross-shaped patch having arms extending along different longitudinal axes, conductive landing pads interposed between the cross-shaped patch and the antenna ground, and vertical conductive legs extending between each of the arms and corresponding landing pads. The antenna may be fed using a first antenna feed coupled between a first of the landing pads and the antenna ground and a second antenna feed coupled between a second of the landing pads and the antenna ground. The landing pads, antenna ground, and cross-shaped patch may be formed from conductive traces on different layers of a dielectric substrate.

    Abstract: An electronic device may be provided with a sidewall and an antenna module pressed against an interior surface of the sidewall. The module may include a phased antenna array. The sidewall may have apertures aligned with respective antenna in the array. The antennas may convey radio-frequency signals in first and second frequency bands greater than 10 GHz and with vertical and horizontal polarizations. Each aperture may include a corresponding cavity with non-linear cavity walls. The antennas may excite resonant cavity modes of the cavities that cause the cavities to radiate the radio-frequency signals as waveguide radiators. At the same time, the apertures may form a smooth impedance transition between the antennas and free space for the radio-frequency signals of both the horizontal and vertical polarizations.

    Abstract: An electronic device may be provided with an antenna module and a phased antenna array on the module. The module may include a logic board, an antenna board surface-mounted to the logic board, and a radio-frequency integrated circuit (RFIC) mounted surface-mounted to the logic board. The phased antenna array may include antennas embedded in the antenna board. The antennas may radiate at centimeter and/or millimeter wave frequencies. The logic board may form a radio-frequency interface between the RFIC and the antennas. Transmission lines in the logic board and the antenna board may include impedance matching segments that help to match the impedance of the RFIC to the impedance of the antennas. The module may efficiently utilize space within the device without sacrificing radio-frequency performance.

    Abstract: An electronic device may be provided with a display and a phased array antenna that transmits radio-frequency signals at frequencies greater than 10 GHz. The display may include a conductive layer that is used to form pixel circuitry and/or touch sensor electrodes. A filter may be formed from conductive structures within the conductive layer. The conductive structures may include an array of conductive patches separated by slots or may include conductive paths that define an array of slots. The filter may include an additional array of conductive patches stacked under the array of conductive patches to allow the slots to be narrower than would be resolvable to the unaided human eye. The periodicity of the conductive structures and the slots in the filter may be selected to tune a cutoff frequency of the filter to be greater than frequencies handled by the phased antenna array.

    Abstract: An electronic device may be provided with wireless circuitry for conveying radio-frequency signals greater than 10 GHz. The wireless circuitry may include a phased antenna array that transmits a steerable signal beam and independent antennas that are separate from the array. The array may be coupled to a first transceiver and the independent antennas may be coupled to a second transceiver. Power amplifier stages may be coupled between the second transceiver and the independent antennas to boost the gain of the independent antennas. If desired, the array and the independent antennas may be coupled to ports of the same transceiver. In this arrangement, each independent antenna may include an antenna feed that is coupled to a respective pair of ports on the transceiver. This may serve to boost the gain of the independent antennas without power amplifier circuitry. The independent antennas may have smaller footprints than the phased antenna array.
