Abstract

In this article, a novel miniaturized frequency selective surface (FSS) is presented, in which each periodic cell consists of a ring slot resonator loaded with four ceramic chip capacitors for reducing the cell size. To eliminate the undesired coupling between unit cells, the unit cell is placed in the substrate integrated waveguide cavity structure. A S‐band bandpass FSS with such structures is designed and fabricated, both simulated and measured results show that the proposed FSS provides high transmission at 2.45 GHz and there is no other frequency resonance up to 15 GHz. Also, it has very good stability to oblique incidence. Furthermore, the dimension of the proposed FSS is miniaturized to 0.083λ~0~ (λ~0~ refer to the resonant wavelength). © 2008 Wiley Periodicals, Inc.
