8. A headset device comprising:
a housing;
a display mounted to the housing, having an active area containing an array of pixels, and having an inactive border region free of pixels;
a substrate in the housing and having a surface;
a phased antenna array mounted under the inactive border region of the display and having a plurality of antenna elements disposed on the surface of the substrate; and
a radome formed from a portion of the housing and having an outer surface and an inner surface between the outer surface and the plurality of antenna elements, the outer surface of the radome being a curved surface, wherein the phased antenna array is operable to convey wireless radio-frequency signals as a signal beam through the radome, the radome has a first thickness in a first portion overlapping each antenna element in the plurality of antenna elements and a second thickness different than the first thickness in a second portion adjacent to the first portion, the phased antenna array and the substrate are separated from the radome by an air gap across an area of the radome that overlaps the phased antenna array and the substrate, and the radome includes a plurality of recesses at the inner surface each overlapping a corresponding one of the plurality of antenna elements.
