Abstract
To provide a frequency selective surface of which an operating frequency and a bandwidth thereof can be readily adjusted. A frequency selective surface structured such that resonators kformed by conductive patterns with a same shape are periodically arranged on a dielectric substrate, wherein the resonator kincludes: a conductor wire part with a lateral patternand a longitudinal patternwhich form a cross above a dielectric substrate; and an electrode plate part created by extending, in directions in which the lateral pattern and the longitudinal pattern are orthogonal to each other, respective both end parts of the lateral pattern and the longitudinal pattern having been extended by a prescribed length, the electrode plate part being shaped such that a tip portion thereof opposes a tip portion extended from another direction at an interval above a diagonal line, and the electrode plate part is shaped such that a central portion opposing an electrode plate part of another adjacent resonator is notched in a width of the lateral pattern, the electrode plate part being joined with the electrode plate part of the other adjacent resonator by being extended from a center of the notched portion in a width that is narrower than the width of the lateral patternand in a length that is shorter than the prescribed length, and the interval of the tip portion is wider than an interval with the electrode plate part of the other adjacent resonator.
