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 include a conductive housing with a rear wall and a sidewall. A display may be mounted to the sidewall and may include a conductive display structure separated from the sidewall by a slot. An antenna arm may be interposed between the conductive display structure and the rear wall. A first inductor may couple the conductive display structure to the housing and may compensate for a distributed capacitance between the antenna arm and the conductive display structure. A second inductor may couple the antenna arm to the rear wall and may compensate for a distributed capacitance between the antenna arm and the rear wall. A speaker may be co-located with the antenna. A third inductor may couple the antenna arm to the rear wall to allow antenna currents to bypass the speaker.

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.

Abstract: An electronic device may have a first conductive sidewall at an upper end, a second conductive sidewall at a lower end, and a conductive rear wall. First and second antennas may be formed at the upper end and may include slots with edges defined by the first sidewall and the rear wall. Third, fourth, fifth, and sixth antennas may be formed at the lower end and may include slots with edges defined by the second sidewall and the rear wall. Each antenna may cover multiple frequency bands. First order and third order modes of the slots may contribute to the frequency responses of the third through sixth antennas. A display controller may be mounted at the lower end and may impose a lower limit on the frequencies covered by the third through sixth antennas. The first and second antennas may cover lower frequencies than the third through sixth antennas.

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.

Abstract: An electronic device may be provided with a phased antenna array and a display cover layer. The phased antenna array may include a dielectric resonator antenna. The dielectric resonator antenna may include a dielectric resonating element embedded in a lower permittivity dielectric substrate. The substrate and the resonating element may be mounted to a flexible printed circuit. A slot may be formed in ground traces on the flexible printed circuit and aligned with the resonating element. The slot may excite resonant modes of the resonating element. The resonating element may convey corresponding radio-frequency signals through the cover layer. A dielectric matching layer may be interposed between the resonating element and the cover layer. If desired, the slot may radiate additional radio-frequency signals and the matching layer may have a tapered shape. Dielectric resonator antennas for covering different polarizations and frequencies may be interleaved across the array.

Abstract: An electronic device may have peripheral conductive structures and a conductive layer that define edges of a slot element for a slot antenna. The slot element may be configured to cover wireless communications in a 1575 MHz satellite navigation band and 2.4 GHz and 5 GHz wireless local area network bands. A tuning circuit may be coupled across the slot approximately half way across the length of the slot. The antenna tuning circuit may include an inductor coupled in series with a notch filter (in scenarios where the slot is long enough to cover the 1575 MHz satellite navigation band in its fundamental mode) or may include a capacitor coupled in series with a notch or low pass filter. The fundamental mode and one or more harmonic modes of the slot element may cover the satellite navigation and wireless local area network bands.

Abstract: An electronic device may be provided antennas and control circuitry. The antennas may be arranged in an array of unit cells. Each unit cell may include a first antenna that conveys signals in a first frequency band higher than 10 GHz and a second antenna that conveys radio-frequency signals in a second frequency band higher than the first frequency band. A first of the unit cells may be provided with a first set of antennas that transmits radio-frequency signals in a third frequency band higher than the second frequency band. A second of the antenna unit cells may be provided with a second set of antennas that receives the radio-frequency signals after being reflected off of external objects. The control circuitry may perform spatial ranging operations by processing the transmitted and received signals in the second frequency band.

Abstract: An electronic device may be provided an antenna, a display, and a housing. The display may include a conductive display structure and a cover layer. The housing may include peripheral conductive structures and a conductive rear wall. The peripheral structures may include a ledge separated from the conductive display structure by a gap. The peripheral structures and the rear wall may define opposing edges of a slot element for the antenna. Conductive bridging structures may be coupled between the conductive display structure and the ledge across the gap. The bridging structures may at least partially overlap locations along the length of the slot element where antenna currents around the slot element exhibit a maximum magnitude. The bridging structures may align the phase of current induced on the ledge with the phase of the current induced on the conductive display structure to maximize antenna efficiency through the cover layer.

Abstract: An electronic device may be provided with a sidewall, a display module separated from the sidewall by a gap, a display cover, a conductive bucket mounted to the display cover within the gap, and a phased antenna array mounted to the bucket for conveying millimeter wave signals through the display cover. The sidewall may form part of an antenna for conveying non-millimeter wave signals. The array may include resonating elements on a substrate. The resonating elements may be fed using feed terminals coupled to alternating sides of the resonating elements. Dielectric layers having a dielectric constant lower than that of the display cover may be provided on a surface of the display cover within the bucket. The array may operate with satisfactory efficiency despite the small amount of available space within the device, electromagnetic interference from the sidewall and the display module, and dielectric loading by the display cover.
