Abstract
A horn antenna is formed within a multilayer substrate and has a generally trapezoidal shaped top plate and bottom plate formed in different layers of the multilayer substrate. A set of densely spaced vias form two sidewalls of the horn antenna by coupling adjacent edges of the top plate and the bottom plate. The horn antenna has a narrow input end and a wider flare end. A microstrip line is coupled to the top plate and a ground plane element is coupled to the bottom plate at the input end of the horn antenna.
