RIDGE GAP WAVEGUIDE AND MULTILAYER ANTENNA ARRAY INCLUDING THE SAME

WIPO Patent Application WO/2020/116934

A1

Disclosed is a ridge guide waveguide including a conductive base, a conductive ridge protruding upward from the conductive base and extending along a predetermined wave transmission direction, an upper conductive wall located over the conductive base and the conductive ridge and spaced apart from the conductive ridge by a gap, and an electromagnetic bandgap structure arranged adjacent to the conductive ridge between the conductive base and the upper conductive wall.
