ABSTRACT:
A plurality of conductive strip elements compose multilayer loading structures on top and bottom surfaces of a dielectric transmission substrate, by which a part of intra-substrate transmission components of a electromagnetic wave are leaked out of the surfaces. Each multilayer loading structure includes a first conductive strip group of conductive strip elements within a first plane, and a second conductive strip group of conductive strip elements within a second plane, and the first and second conductive strip groups are formed to be capacitively coupled to each other. In each of the first and second conductive strip groups, the conductive strip elements are placed at intervals of a distance of a quarter or less of a reference adjacent distance, where the reference adjacent distance is defined as a distance for generating spatial harmonics of the electromagnetic wave on the surfaces of the dielectric transmission substrate.
