A NOVEL Y-LOOP APERTURE FREQUENCY SELECTIVE SURFACE USING SUBSTRATE-INTEGRATED WAVEGUIDE TECHNOLOGY

In this article, a novel Y-loolp frequency-selective surface (FSS) is proposed based on substrate-integrated waveguide (SIW) technology. This novel Y-loop FSS is analyzed by Ansoft HFSS simulation tool. It can be observed that the proposed Y-loop aperture FSS has higher selectivity for reducing the relative bandwidth about 5%, and more stable bandwidth at different polarization states and in various directions compared with the conventioaal Y-loop FSS. The effectiveness of the novel Y-loop aperture FSS is validated by good agreement between the simulated results and the measured results. (C) 2008 Wiley Periodicals. Inc.
