Abstract: An electronic device may have an antenna embedded in a substrate. The substrate may have first layers, second layers on the first layers, and third layers on the second layers. The antenna may include a first patch on the first layers that radiates in a first band, a second patch on the second antenna layers that radiates in a second band, and a parasitic patch on the third layers. A short path may couple ground to a location on the first patch that allows the first patch to form a ground extension in the second band for the second patch without affecting performance of the first patch in the first band. The first layers may have a higher dielectric permittivity than the second and third layers to minimize the thickness of the substrate without requiring a separate dielectric loading layer over the substrate.

Abstract: An electronic device may have an antenna that conveys radio-frequency signals at frequencies greater than 10 GHz. The antenna may be embedded in a substrate. The substrate may have routing layers, first antenna layers on the routing layers, second antenna layers on the first antenna layers, and a third antenna layers on the second antenna layers. The antenna may include first traces on the first antenna layers, second traces on the second antenna layers, and third traces on the third antenna layers. The first antenna layers may have a first bulk dielectric permittivity. The second layers may have a second bulk dielectric permittivity. The third layers may have a third bulk dielectric permittivity. At least one of the first, second, and third bulk dielectric permittivities may be different from the others. This may differentially load the antenna across the antenna layers, thereby broadening the bandwidth of the antenna.

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 include first and second phased antenna arrays and a triplet of first, second, and third ultra-wideband antennas. An antenna module in the device may include a dielectric substrate. The first and second arrays and the triplet may be formed on the dielectric substrate. The third and second ultra-wideband antennas may be separated by a gap. The first array may be laterally interposed between the third and second ultra-wideband antennas within the gap. The third ultra-wideband antenna may be laterally interposed between the first phased antenna array and at least some of the second array. An integrated circuit may be mounted to the dielectric substrate using an interposer. The antenna module may occupy a minimal amount of space within the device and may be less expensive to manufacture relative to scenarios where the arrays and the ultra-wideband antennas are formed on separate substrates.

Abstract: An electronic device may have a phased antenna array. An antenna in the array may include a rectangular patch element with diagonal axes. The antenna may have first and second antenna feeds coupled to the patch element along the diagonal axes. The antenna may be rotated at a forty-five degree angle relative to other antennas in the array. The antenna may have one or two layers of parasitic elements overlapping the patch element. For example, the antenna may have a layer of coplanar parasitic patches separated by a gap. The antenna may also have an additional parasitic patch that is located farther from the patch element than the layer of coplanar parasitic patches. The additional parasitic patch may overlap the patch element and the gap in the coplanar parasitic patches. The antenna may exhibit a relatively small footprint and minimal mutual coupling with other antennas in the array.

Abstract: An electronic device may be provided with an antenna module having a substrate. A phased antenna array of dielectric resonator antennas and a radio-frequency integrated circuit for the array may be mounted to one or more surfaces of the substrate. The dielectric resonator antennas may include dielectric columns excited by feed probes. The feed probes may be printed onto sidewalls of the dielectric columns or may be pressed against the sidewalls by biasing structures. A plastic substrate may be molded over each dielectric column and each of the feed probes in the array. The feed probes may cover multiple polarizations. The array may include elements for covering multiple frequency bands. The dielectric columns may be aligned a longitudinal axis and may be rotated at a non-zero and non-perpendicular angle with respect to the longitudinal axis.

Abstract: An electronic device may be provided with wireless communications circuitry and control circuitry. The wireless communications circuitry may include centimeter and millimeter wave transceiver circuitry and a phased antenna array. A dielectric cover may be formed over the phased antenna array. The phased antenna array may transmit and receive wireless radio-frequency signals through the dielectric cover. The dielectric cover may have first and second opposing surfaces. The second surface may face the phased antenna array and may have a curvature. The curvature of the second surface may include one or more recessed regions of the dielectric cover. The one or more recessed regions of the second surface may serve to maximize and broaden the coverage area for the phased antenna array. The first surface may be conformal to other structures in the electronic device.

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.

Abstract: An electronic device may include a phased antenna array mounted in a conductive cavity for conveying radio-frequency signals above 10 GHz. The cavity may include sidewalls extending from a rear wall. The array may include rectangular patches each having first and second perpendicular edges. Each of the first edges in the array may be aligned with a first axis. Each of the second edges in the array may be aligned with a second axis perpendicular to the first axis. The first and second axes may be oriented at 45 degrees with respect to each of the sidewalls of the cavity. Each patch may be fed using first and second positive antenna feed terminals that cover orthogonal linear polarizations. The cavity may prevent interference while symmetrically loading the impedance of both the first and second positive antenna feed terminals in each patch.

Abstract: An electronic device such as a wristwatch may be provided with wireless circuitry and a display having a display module and a cover layer. The display module may include a dielectric layer. Touch sensor electrodes may be formed from conductive traces on the dielectric layer. An antenna may be embedded within the display module. The antenna may include an antenna resonating element formed from a grid of intersecting conductive traces on the dielectric layer. The grid may have edges that define a lateral outline of the antenna resonating element. The outline may have a length that configures the antenna to radiate at a desired frequency. The antenna resonating element may be formed from indium tin oxide and may be substantially transparent.
