  • Publication number: 20200021025
    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.

  • Publication number: 20200021019
    Abstract: An electronic device may be provided with antenna structures that convey radio-frequency signals greater than 10 GHz. The antenna structures may include overlapping first and second patches. The first patch may include a hole. A transmission line for the second patch may include a conductive via extending through the hole. The via may be coupled to a first end of a trace. A second end of the trace may be coupled to a feed terminal on the second patch over an additional via. The hole may be located within a central region of the first patch to allow the via to pass through the hole without electromagnetically coupling to the first patch. If desired, adjustable impedance matching circuits may be used to couple selected impedances to the antenna feeds that help ensure that the first and second patch antennas are sufficiently isolated from each other.

  • Publication number: 20190379134
    Abstract: An electronic device may be provided with wireless circuitry. The wireless circuitry may include one or more antennas and transceiver circuitry such as centimeter and millimeter wave transceiver circuitry (e.g., circuitry that transmits and receives antennas signals at frequencies greater than 10 GHz). The antennas may be arranged in a phased antenna array. The phased antenna array may be formed on a dielectric substrate and may include one or more indirectly-fed microstrip dipole antennas. Conductive traces forming dipole antenna resonating elements or parasitic resonating elements for the dipole antennas in the phased antenna array may be embedded within or formed on an upper surface of the dielectric substrate. The phased antenna array may include both dipole antennas and patch antennas. Dipole antennas may be interposed between adjacent patch antennas or formed next to patch antennas.

  • Patent number: 10476170
    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.

  • Publication number: 20190319367
    Abstract: An electronic device may be provided with a dielectric cover layer, a dielectric substrate, and a phased antenna array on the dielectric substrate for conveying millimeter wave signals through the dielectric cover layer. The array may include conductive traces mounted against the dielectric layer. The conductive traces may form patch elements or parasitic elements for the phased antenna array. The dielectric layer may have a dielectric constant and a thickness selected to form a quarter wave impedance transformer for the array at a wavelength of operation of the array. The substrate may include fences of conductive vias that laterally surround each of the antennas within the array. When configured in this way, signal attenuation, destructive interference, and surface wave generation associated with the presence of the dielectric layer over the phased antenna array may be minimized.

  • Publication number: 20190267709
    Abstract: An electronic device may be provided with wireless circuitry that includes a phased antenna array. The array may include multiple antennas each having multiple antenna feeds for covering different polarizations. Control circuitry may control the wireless circuitry to transmit signals at millimeter or centimeter wave frequencies using a first set of feeds in the array and at least one selected phase. The wireless circuitry may receive the signals transmitted by the first set of feeds using a second set of feeds in the array. The control circuitry may gather phase measurements for the received signals and may compare the phase measurements to the selected phase to generate phase difference values. The control circuitry may perform external object proximity detection operations based on the phase difference values. The control circuitry may control the wireless circuitry to cycle through different combinations of antenna feeds for the first and second sets.

  • Publication number: 20190257933
    Abstract: 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.

  • Publication number: 20190027802
    Abstract: 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.

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.

  • Publication number: 20190020114
    Abstract: An electronic device may include a millimeter wave antenna having a ground plane, resonating element, feed, and parasitic element. The resonating element may include first, second, and third layer of traces that are shorted together. The second traces may be interposed between the first and third traces and the third traces may be interposed between the second traces and the parasitic. The third traces may have a width that is less than the widths of the second and third traces. The third traces and the parasitic may define a constrained volume having an associated cavity resonance that lies outside of a frequency band of interest. If desired, the resonating element may include a single layer of conductive traces having a grid of openings that disrupt impedance in a transverse direction, thereby mitigating the trapping of energy within the frequency band of interest between the resonating element and the parasitic.
