Tunable mechanically reconfigurable frequency selective surface based on rotating rigid structures

Abstract

Provided is a tunable mechanically reconfigurable frequency selective surface based on rotating rigid structures, including N frequency selective surface units which are arranged in an arrangement of a periodic shape array. The frequency selective surface unit includes four frequency selective surface subunits, the frequency selective surface subunit includes a dielectric substrate and an annular conductive layer; the annular conductive layer is arranged on a surface of the dielectric substrate, and the four frequency selective surface subunits are connected in such a way that angles between adjacent frequency selective surface subunits are α degrees, 180-α degrees, α degrees and 180-α degrees.

Dependencies are inferred from the claim text.
