1. A dielectric structure positioned adjacent to an active element of an antenna for a radio frequency (RF) application, the dielectric structure comprising:
a plurality of individual layers in a stacked layer arrangement including a first layer having a top surface and an opposing bottom surface and including a first RF dielectric material, a second layer adjacent to and in contact with the first layer, the second layer having a top surface and an opposing bottom surface and including a second RF dielectric material, a third layer adjacent to and spaced apart from the second layer by a predetermined distance to form a gap layer between the second layer and the third layer; a passage in the third layer configured to route a grounding line to a ground element of the antenna, the ground element disposed below the third layer; and at least one non-conductive mechanical fastening mechanism configured to couple the plurality of individual layers to one another and to inhibit short-circuiting the active element with the ground element of the antenna.
