Abstract
Provided is a tunable frequency selective surface (FSS) structure, including: a dielectric substrate and a rectangle resonant component arranged on the dielectric substrate. The rectangle resonant component includes a plurality of perforated rectangle resonant units arranged in a matrix; the perforated rectangle resonant units each include two identical rectangle perforated metal patches, and a varactor diode arranged between the two rectangle perforated metal patches, where the two rectangle perforated metal patches are arranged in a mirror image relation. In the rectangle resonant component, the varactor diodes in the perforated rectangle resonant units in the same row are arranged in a same direction, and the varactor diodes in the perforated rectangle resonant units in adjacent rows are arranged in opposite directions. The present application can achieve the continuous tunable performance of a stopband in a specific frequency band.
