Abstract
Provided is a frequency selective surface including a conductor plane (101), nine loop slots (102) each formed to be surrounded by the conductor plane (101), and a capacitance component (103) disposed to straddle the loop slots (102) in a width direction, both ends of the capacitance component being connected to the conductor plane (101) at a position near the loop slots (102). The conductor plane (101) and the loop slots (102) each 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) disposed to straddle the loop slots (102) in the width direction are provided for each loop slot (102). Operating frequencies can be easily changed by adjusting only a component connected to the unit cell, or a part of metallic patterns.
