  • Directive fixed beam ramp EBG antenna
    Patent number: 10249953
    Abstract: A fixed beam ramp electromagnetic band gap (EBG) antenna including a radiating element and an electromagnetic band gap (EBG) structure both disposed within a ramped cavity. The cavity is designed with the ramp leading to the EBG structure disposed about a base of the cavity. The radiating element can be disposed above the EBG structure and the EBG structure may have a plurality of unit cells. The EBG structure can be provided both, horizontally on the floor of the cavity and vertically along a back wall of the cavity. The use of both horizontal and vertical EBG structures combined with the ramped cavity increases the bandwidth and enhances the beam steering of the antenna system.
