1. A waveguide structure, comprising:
- a first conductive plane continuously laid out in a predetermined area;
a second conductive plane laid in parallel with the first conductive plane; and
a plurality of unit structures, each of which includes;
a transmission line having a first end serving as an open end and a second end, the transmission line being formed in a different layer than the first conductive plane and the second conductive plane, and an entirety of the transmission line being disposed opposite to the second conductive plane such that the transmission line is positioned relatively close to the second conductive plane; and
a conductive via electrically connecting the transmission line to the first conductive plane, the conductive via connected to the second end of the transmission line,wherein the unit structures are repetitively aligned in a one-dimensional manner or in a two-dimensional manner over the predetermined area, andwherein the transmission line is formed inside a region interposed between the first conductive plane and the second conductive plane.

Abstract
A waveguide structure or a printed-circuit board is formed using a plurality of unit structures which are repetitively aligned in a one-dimensional manner or in a two-dimensional manner. The unit structure includes first and second conductive planes which are disposed in parallel with each other, a transmission line having an open end which is formed in a layer different from the first and second conductive planes and positioned to face the second conductive plane, and a conductive via electrically connecting the transmission line to the first conductive plane.
