Abstract

Two bandpass filters (BFFs) for ultra-wideband (UWB) applications are proposed using the uniplanar compact-electromagnetic bandgap (UC-EBG) and the foliated UC-EBG (FUC-EBG) structures for size reduction. The sizes of the proposed UWB BFFs are reduced by 20 - 22% compared to the conventional one with the microstrip multiple-mode resonator (MMR). Both EBG structures are shown to cause a slow-wave effect, which is required for compactness and the characteristic impedance Zc close to 50 Ω, which is needed for wideband match.
