Patent ID: 8890761

Claim:
A structure comprising: a first conductor plane; a plurality of second conductor planes that are substantially parallel to the first conductor plane; a transmission line that is substantially parallel to the first conductor plane; and a first conductor connecting portion that is electrically connected to the transmission line, wherein: one conductor plane of the first conductor plane and the plurality of second conductor planes does not contact the transmission line, an other conductor plane of the first conductor plane and the plurality of second conductor planes is electrically connected to the transmission line, the one conductor plane is disposed between the other conductor plane and the transmission line, the one conductor plane is a single conductor plane with an opening that is not continuous with a periphery of the one conductor plane, the transmission line overlaps the one conductor plane in a direction perpendicular to the first conductor plane, except in a portion of the transmission line that faces the opening of the one conductor plane, the one conductor plane is a return path of the transmission line, and a plurality of unit structures each including at least the second conductor plane, the transmission line, and the first conductor connecting portion are repeatedly disposed.
