Abstract
Embodiments of the present disclosure relate to a substrate integrated waveguide monopulse antenna. The antenna comprises a substrate having first and second opposing surfaces. A first conductor is disposed on the first surface of the substrate. A plurality of antenna elements are provided on the first surface of the substrate. A second conductor is disposed on the second surface of the substrate. A plurality of conductive via holes extend through said substrate and extend between the first and second surfaces. The via holes are arranged to form a plurality of resonant cavities with at least one resonant cavity coupled to each of the antenna elements. The substrate also comprises a plurality of hybrid couplers, and two of the plurality of resonant cavities are coupled to at least one port of the plurality of hybrid couplers. A plurality of output couplers provided on the second surface of the substrate.
