Summary:To increase reception gain.SOLUTION: A periodic structure includes a cylindrical conductor layer and a cylindrical laminate. The laminate is disposed in an inner periphery of the conductor layer, where multiple layers of frequency selection plates in which multiple elements are periodically disposed are laminated. In the element, at least part of peripheral edge facing adjacent elements in the layer is formed toward the center of element.SELECTED DRAWING: Figure 4 【課題】受信利得を向上させること。【解決手段】本実施形態に係る周期構造体は、円筒形状の導体層と、円筒形状の積層体とを含む。積層体は、前記導体層の内周に配置され、複数の素子が周期的に配置される周波数選択板の層が複数積層される。前記素子は、層内で隣接する素子と対向する辺縁の少なくとも一部分が素子中央に向かって形成される。【選択図】図４
