Abstract

A new miniaturized bandpass fractal frequency selective surface (FSS) with excellent angular stability performa nce is proposed. The minia turization has been achieved by scheming out a symmetric fractal pattern of continuous slots from the surface of a square-shaped patch, in which each periodic cell consists of incurved slot resonator for reducing the cell size. Reduction in FSS size of up to 74% with respect to the conventional square loop aperture FSS operating at the same frequency of 3.3 GHz is obtained. Furthermore, results show excellent angular stability for both vertica land horizontal polarization at different incidence angles because of its fractal configuration. A prototype is fabricated and the FSS measurement, and simulation results are presented and discussed.
