Abstract
The invention provides a frequency selective surface structure including a substrate and at least one conductive layer. The at least one conductive layer is disposed on the substrate and includes four central double-frequency patches. The four central double-frequency patches are spaced apart from one another and are arranged in a 2×2 array. In each of the four central double-frequency patches, the central double-frequency patch is in a polygonal shape and has a central corner part, a plurality of outer corner parts and a plurality of notches, the central corner part is located closer to a geometric center of the at least one conductive layer than the plurality of outer corner parts, and the plurality of notches are located on the plurality of outer corner parts, respectively.
