Abstract
A waveguide antenna apparatus includes a lower laminate layer of non-radio-frequency (RF) material and a first layer of conductive material formed on a top surface of the lower laminate layer of non-RF material. A middle layer of non-RF material formed over the first layer of conductive material, the middle layer of non-RF material comprising a waveguide cavity formed through the middle layer of non-RF material, such that air forms a propagation medium for radiation in the waveguide cavity. An upper layer of non-RF material is formed over the middle layer of non-RF material, and a second layer of conductive material is formed on a top surface of the upper layer of non-RF material, the first and second layers of conductive material and the waveguide cavity being part of a waveguide antenna.
