摘要: In this article, a novel miniaturized dual-band frequency selective surface (FSS) with close band spacing is presented, in which each periodic cell consists of double square loops different capacitive loadings. The dimension the unit by loading ceramic chip capacitors. To eliminate undesired coupling between cells, cells are placed substrate integrated waveguide cavity structure. As result, FSS designed, both simulated and measured results show that operates over DCS1800 (1.8 GHz) Bluetooth (2.45 range. And to 0.114 λ (λ refers resonant wavelength 1.8 GHz). Furthermore, it has very good stability oblique incidence waves for TE TM polarization. © 2009 Wiley Periodicals, Inc.
