Abstract
A H-plane sectoral horn antenna made from a woodpile electromagnetic bandgap (EBG) material is described. The electromagnetic confinement mechanism within the horn antenna relies wholly on the 3D EBG of the woodpile material, which is flared in the H-plane. The antenna has a typical sectoral horn pattern with a directional beam in one principal plane and a broader beam in the other. In a prototype antenna, a rectangular waveguide-to-EBG waveguide transition is used to deliver energy to the horn. Preliminary theoretical results on radiation patterns and impedance bandwidth of this antenna are described. The bandwidth of the antenna is almost equal to that of the defect waveguide.
