In one example, an antenna assembly includes a cavity structure comprising an interior volume surrounded by a wall and having an opening at a first longitudinal end and a cap at a second longitudinal end. A conductive material disposed on a portion of the wall of the cavity structure and the cap such that a dielectric gap is established between the conductive material and a planar antenna when the planar antenna is coupled onto the first longitudinal end of the cavity structure.
