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 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.
