    Abstract: An electronic device may be provided with a phased antenna array that radiates at a frequency greater than 10 GHz. The array may include a first set of dielectric resonator antennas arranged in a first row and a second set of dielectric resonator antennas in a second row offset from the first row. Each dielectric resonator antenna may have dielectric resonating element with a base portion and a stepped portion. The stepped portions of the antennas in the first set may be arranged to be distant from the stepped portions of the antennas in the second set. The antennas in the first set may be arranged to be more distant from an electronic device sidewall than the antennas in the second set. Configured in this manner, the array may exhibit reduced inter-coupling between dielectric resonator antennas in the first set and dielectric resonator antennas in the second set.

    Abstract: An electronic device may be provided with first and second sidewalls, a rear wall, and a display. Multiple antenna panels may be used to convey radio-frequency signals at frequencies greater than 10 GHz. A first antenna panel may radiate through the display while second and third panels radiate through the first and second sidewalls. The second and third panels may be tilted at non-zero angles with respect to the sidewalls. The non-zero angles may be of opposite sign. The non-zero angles may have the same magnitude. The magnitude may be equal to 15 degrees, as one example. Tilting the panels in this way may allow the panels to collectively cover as much of a sphere around the device as possible, including out of coverage areas behind the rear wall caused by conductive material in the rear wall, without requiring additional panels to be disposed within the device.

    Abstract: An electronic device may be provided with a phased antenna array having a dielectric resonator antenna. The antenna may include a first dielectric block on a printed circuit, a second dielectric block on the first dielectric block, and a third dielectric block on the second dielectric block. At least the second and third dielectric blocks may have different dielectric constants. A parasitic element may be disposed between the second and third dielectric resonating elements and/or a parasitic element may be disposed on a radiative face of the third dielectric resonating element. The parasitic elements may act as electromagnetic mirrors that form images of electric fields in the dielectric resonating elements. The images may make the dielectric resonating elements exhibit a greater electromagnetic height than physical height. This may allow for a reduction in the overall physical height of the dielectric resonator antenna without sacrificing wireless performance.

    Abstract: An electronic device may be provided with a phased antenna array having a dielectric resonator antenna. The antenna may include a first dielectric block on a printed circuit, a second dielectric block on the first dielectric block, and a third dielectric block on the second dielectric block. At least the second and third dielectric blocks may have different dielectric constants. The antenna may be fed by one or more feed probes. Each feed probe may include respective conductive via and a conductive patch coupled to the conductive via. The conductive via may extend through the first dielectric block. The conductive patch may be sandwiched between the first and second dielectric blocks. The conductive patch may have a width that configures the conductive patch to form a smooth impedance transition between the conductive via and each of the dielectric blocks despite the different materials used to form the antenna.
