Abstract
An electromagnetic waveguide including conductive material on upper lower, and side surfaces of a dielectric is disclosed. A conductive excitation member is electrically coupled to the conductive material on the upper surface of the dielectric and extends to the lower surface of the dielectric at or near an end surface of the dielectric. The conductive excitation member includes a host interface flange separated and electrically isolated from the conductive material on the lower surface of the dielectric. The conductive material on the lower surface of the dielectric can be a ground plane and the waveguide can be a surface-mountable component.
