Abstract: An electronic device comprises a housing (12R, 12W, Figure 6), a dielectric cover layer 56, a printed circuit (72, Figure 6), and a phased antenna array configured to radiate at a frequency greater than 10 GHz. The array comprises a plurality of dielectric resonating columns 92 staggered between first and second rows and mounted to the printed circuit, each dielectric column including a non-planar sidewall. The non-planar sidewall may be formed by a step (134, Figure 8) that joins planar sidewalls of first 130 and second 132 portions of each dielectric column. The non-planar sidewall of one row of columns preferably faces a non-planar sidewall of the other row of columns. Each dielectric column may also comprise a planar sidewall across the first and second portions. The array may exhibit reduced inter-coupling between dielectric resonator antennas in the first and second rows. An electronic device comprising a housing having a conductive sidewall (12W, Figure 11), and first and second rows of dielectric columns each having a non-planar sidewall configured to radiate at first and second frequencies respectively is also provided, as well as an antenna comprising a dielectric column having a planar sidewall and a non-planar sidewall.

Abstract: A millimetre wave electronic communication device 10 comprises a dielectric cover layer, a dielectric substrate having a surface mounted against the dielectric cover layer, and a phased antenna array on the dielectric substrate wherein the phased antenna array comprises conductive traces. The phased antenna array is configured to transmit radio-frequency signals between 10 GHz – 300 GHz. A second aspect comprises the dielectric cover layer forming a quarter wave impedance transformer. A third aspect comprises a plurality of conductive trace antennas attached to the dielectric housing wall and a fence of conductive vias extending through the substrate, laterally surrounding each antenna trace. The phased arrays may comprise patch elements and parasitic elements.

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 a dielectric cover layer, a dielectric substrate, and a phased antenna array on the dielectric substrate for conveying millimeter wave signals through the dielectric cover layer. The array may include conductive traces mounted against the dielectric layer. The conductive traces may form patch elements or parasitic elements for the phased antenna array. The dielectric layer may have a dielectric constant and a thickness selected to form a quarter wave impedance transformer for the array at a wavelength of operation of the array. The substrate may include fences of conductive vias that laterally surround each of the antennas within the array. When configured in this way, signal attenuation, destructive interference, and surface wave generation associated with the presence of the dielectric layer over the phased antenna array may be minimized.
