    Abstract: An electronic device may have a first phased antenna array that radiates through a display and a second phased antenna array that radiates through a rear wall. The first array may include a front-facing dielectric resonator antenna and the second array may include a rear-facing dielectric resonator antenna. The front and rear-facing antennas may share a dielectric resonating element. Feed probe(s) may excite a first volume of the dielectric resonating element to radiate through the display and may excite a second volume of the dielectric resonating element to radiate through the rear wall. The dielectric resonating element may have a geometry that helps to isolate the front-facing dielectric resonator antenna from the rear-facing dielectric resonator antenna. The first and second arrays may collectively cover an entire sphere around the device while occupying a minimal amount of volume within the device.

    Abstract: An electronic device may be provided with a phased antenna array having a bent dielectric resonating element. The bent dielectric resonating element may have a first segment, a second segment nonparallel to the first segment, and an angled surface that couples the first segment to the second segment. One or more feed probes may be coupled to the first segment to excite the dielectric resonating element. A reflector may be provided on the angled surface to direct electromagnetic energy from the first segment to the second segment and vice versa. The bent dielectric resonating element may exhibit less overall height than dielectric resonators having straight columns of dielectric material, thereby allowing for a reduction in the thickness of the electronic device. The angled surface and the reflector may optimize the radio-frequency performance of the antenna despite the reduction in overall height.

    Abstract: An electronic device may be provided with a display and conductive sidewalls. The display may include conductive display structures and a cover layer. The cover layer may be mounted to the sidewalls. The sidewalls may define antenna apertures for antennas in the device. Grounding structures may be coupled between the conductive display structures and the sidewalls at locations that at least partially overlap the antenna apertures. The grounding structures may include conductive tape having an adhesive surface. The conductive tape may have a first end at which the adhesive surface is coupled to the conductive display structures. The conductive tape may have a second end that is folded around a layer of heat-activated film and that is coupled to both the display cover layer and the conductive sidewalls. Conductive tape overlapping each antenna aperture may be concurrently assembled into the electronic device as the display is mounted to the sidewalls.

    Abstract: An electronic device may be provided with a phased antenna array that includes a dielectric resonator antenna having a dielectric column mounted to a circuit board. The dielectric column may be embedded in a dielectric substrate such as a plastic overmold. Conductive walls may be disposed on the dielectric substrate and may laterally surround the dielectric substrate and one or more dielectric resonating elements in the phased antenna array. The conductive walls may be grounded. The conductive walls may have a tapered shape. The conductive walls may help to isolate the antenna from electromagnetic influences from nearby conductive components in the electronic device. The conductive walls may form a conductive horn that helps to maximize the gain of the antenna in conveying radio-frequency signals greater than 10 GHz through a display cover layer, housing window, camera sapphire, or rear housing wall.

    Abstract: An electronic device may be provided with a conductive housing sidewall and a phased antenna array that conveys radio-frequency signals at frequencies greater than 10 GHz. Each antenna in the array may radiate through a respective aperture in the sidewall. The antenna module may include a folded flexible printed circuit having a first portion and a second portion that extends from an end of the first portion and that is folded with respect to the first portion. The antennas in the phased antenna array may have antenna resonating elements that are distributed between the first and second portions. Forming the antenna module from a folded flexible printed circuit in this way may serve to minimize the thickness of the antenna module, thereby allowing the antenna module to fit between a ledge of the sidewall and a rear housing wall without occupying excessive space within the device.
