    Abstract: An electronic device may include a phased antenna array. The array may include co-located first and second antennas formed on a dielectric substrate. The first antenna may include a first patch element and multi-layer parasitic structures. The multi-layer parasitic structures may include a first set of co-planar parasitic elements. The first set of parasitic elements may overlap the first patch element and may be separated by a gap. The multi-layer parasitic structures may include an additional parasitic element that overlaps the gap. The second antenna may include a second patch element that is co-planar with the additional parasitic patch. The second patch element may at least partially overlap one of the parasitic elements in the first set. The first and second patch antennas may collectively cover first and second frequency bands while occupying a minimal amount of space on the dielectric substrate.

    Abstract: An electronic device may be provided with a dielectric cover and a phased antenna array for conveying millimeter wave signals. A conductive pocket may be mounted to the cover. The pocket may include a conductive rear wall and conductive sidewalls that extend from a periphery of the rear wall to the cover. The array may be mounted to the rear wall and may convey signals through the cover. The sidewalls may extend from the cover at non-zero angles with respect to the normal axis of the cover. The shape of the pocket and the cover may be selected so that the pocket is non-resonant at frequencies handled by the array, to mitigate destructive interference within the pocket, to block surface waves from propagating along the cover, and to tweak the radiation pattern of the array to exhibit a desired shape and directionality.

    Abstract: A wireless power transmission system may include a wireless power transmitting device such as a tablet computer and a wireless power receiving device such as a computer stylus. A wireless power transmitting capacitor electrode may be formed in the tablet computer. A wireless power receiving capacitor electrode may be formed in the computer stylus. The transmitting capacitor electrode may be driven by a drive signal having a frequency of 900 MHz or greater to produce wireless power. The wireless power may be transmitted from the transmitting capacitor electrode to the receiving capacitor electrode on the stylus via near field capacitive coupling. The transmitting and receiving capacitor electrodes may each include conductive traces on dielectric substrates. The conductive traces may follow meandering paths to maximize the possible capacitive coupling efficiency between the capacitor electrodes and thus the end-to-end charging efficiency of the wireless power transmission system.

    Abstract: An electronic device may be provided with wireless circuitry. The wireless circuitry may include one or more antennas. The antennas may include millimeter wave antenna arrays. Non-millimeter-wave antennas such as cellular telephone antennas may have conductive structures separated by a dielectric gap. In a device with a metal housing, a plastic-filled slot may form the dielectric gap. The conductive structures may be slot antenna structures, inverted-F antenna structures such as an inverted-F antenna resonating element and a ground, or other antenna structures. The plastic-filled slot may serve as a millimeter wave antenna window. A millimeter wave antenna array may be mounted in alignment with the millimeter wave antenna window to transmit and receive signals through the window. Millimeter wave antenna windows may also be formed from air-filled openings in a metal housing such as audio port openings.

    Abstract: An electronic device may include a substrate and a conductive layer on the substrate. The conductive layer may be patterned to form a first region and a second region that surrounds and defines the shape of the first region. The first region may be formed from a continuous portion of the conductive layer. The second region may include a grid of openings that divides the conductive layer into an array of patches. The first region may form an antenna resonating element for an antenna. The second region may block antenna currents from the antenna resonating element and may be transparent to radio-frequency electromagnetic waves. The openings may have a width that is too narrow to be discerned by the human eye. This may configure the first and second regions to appear as a single continuous conductive layer despite the fact that an antenna resonating element is formed therein.
