The present invention comprises a conductor plane (101), nine loop slots (102) each formed to be surrounded by the conductor plane (101), and a capacitance component (103) disposed so as to stride across the loop slot (102) in a width direction and having both ends connected to the conductor plane (101) at positions close to the loop slot (102). The conductor plane (101) and the loop slot (102) formed to be surrounded by the conductor plane (101) constitute a unit cell (110). The unit cells (110) are two-dimensionally periodically arranged. One or more (four in the case of Fig. 1) capacitance components (103), which are placed so as to stride across each of the loop slots (102) in the width direction, are provided for each of the loop slots (102). Provided is a frequency selective surface the operating frequency of which can be easily changed by adjusting only part of a component connected to a unit cell or a metal pattern. |
