  • Patent number: 10992057
    Abstract: An electronic device may be provided with a cover layer and a phased antenna array mounted against the cover layer. Each antenna in the array may include a first patch element that is directly fed using first and second feeds and a second patch element that is directly fed using third and fourth feeds. A slot element may be formed in the first patch element. The first patch element may radiate in a first frequency band through the cover layer. The slot element may radiate in a second frequency band that is higher than the first frequency band through the cover layer. The second patch element may indirectly feed the slot element. Locating the radiating elements for each frequency band in the same plane may allow the antenna to radiate through the cover layer in both frequency bands with satisfactory antenna efficiency.

  • Patent number: 10978797
    Abstract: An electronic device may be provided with a dielectric cover layer and a conductive layer on the dielectric cover layer. The conductive layer may define an opening. A dielectric spacer may be mounted to the cover layer within the opening. A substrate may be mounted to the spacer. Vertical conductive structures may extend from the conductive layer to the substrate and may laterally surround the spacer. A phased antenna array may be formed on the substrate and aligned with the opening. The cover layer may have a dielectric constant and thickness that are selected to form a quarter wave impedance transformer for the array at a wavelength of operation of the array. The spacer and the conductive structures may exhibit a cavity resonance at the wavelength. The array and the conductive structures may radiate radio-frequency signals at millimeter wave frequencies through the dielectric cover layer.

  • Patent number: 10978777
    Abstract: A system such as a vehicle may have windows. A window may have a structural window layer formed from one or more glass layers. A conductive coating such as an infrared-light blocking coating or other optical filter layer may be formed on the window. The conductive coating may include one or more silver layers or other conductive material. Unpatterned portions of the conductive coating are conductive along orthogonal dimensions. A region of the conductive coating may have parallel line-shaped openings that render the coating conductive in only a single dimension while enhancing radio transparency. Another region of the conductive coating may have a two-dimensional pattern of openings such as a mesh-shaped opening formed from intersecting straight and/or curved lines. In this region, the coating is locally rendered insulating and radio-frequency transparent. Antennas and ohmic heating elements may be formed in the coating.

  • Publication number: 20210096515
    Abstract: An electronic device such as a wristwatch device may have a housing with metal sidewalls and a display module having conductive display structures. The conductive display structures may be separated from the sidewalls by a slot element for a first antenna that runs around the display module. A feed element for the first antenna may be coupled between the display structures and the sidewalls. An antenna resonating element for a second antenna may be disposed within the slot element. A printed circuit may include additional antenna elements for the second antenna. The antenna resonating element may extend away from the feed element for the first antenna to provide improved isolation between the two antennas. The first antenna may be operable to provide coverage for frequencies that are lower than frequencies for which the second antenna may be operable to provide coverage.

  • Patent number: 10965008
    Abstract: An electronic device housing may have a rear housing wall that forms a metal ground plane. A slot may be formed in the metal ground plane. The slot may have one or more open ends along an edge of the ground plane. A near-field communications loop antenna may overlap the slot.

  • Publication number: 20210075094
    Abstract: An electronic device may include a rear housing wall, antenna resonating element, coil, sensor board, and antenna grounding ring structures. The coil may receive wireless charging signals through the grounding ring structures and the rear housing wall. The grounding ring structures may include concentric ring-shaped traces. The ring-shaped traces may be separated by at least one gap. The ring-shaped traces and the gaps may configure the grounding ring structures to short antenna currents at relatively high frequencies from the antenna resonating element to a ground trace on the sensor board while blocking currents at relatively low frequencies. This may allow the ground trace to form part of an antenna without substantially impairing wireless charging efficiency of the coil.

  • Publication number: 20210075090
    Abstract: An electronic device may have peripheral conductive housing structures divided into first and second segments. First and second antennas may be formed from the segments and may be fed using a flexible printed circuit structure. The structure may include a first substrate attached to the first segment, a second substrate soldered to the first substrate and attached to the second segment, and a third substrate soldered to the second substrate. Third and fourth antennas may be formed on the first substrate whereas fifth and sixth antennas are be formed on the second substrate. The second substrate may be folded and may have a lateral area oriented perpendicular to the third, fourth, fifth, and sixth antennas. Modularly forming the structure in this way may maximize the flexibility with which the structure can accommodate other components, thereby minimizing the space consumption associated with mounting and feeding the antennas without sacrificing wireless performance.
