Abstract

The radio wave control board includes: a plurality of unit structures arranged in a first surface direction; and a reference conductor having a reference potential for the plurality of unit structures. The plurality of unit structures are provided with: a first resonator that expands in a first surface direction; and a second resonator that is formed on the same plane as the first resonator, is electromagnetically connected to the reference conductor, and includes first and second resonance structures that are rotationally symmetrical in the first plane direction. The first resonance structure and the second resonance structure are disposed such that the first resonator and the second resonator face each other with a gap therebetween in the first direction.
