Abstract

本研究では,準ミリ波帯においてサイズの小型化と加工性を同時に達成できるSIW構造を用いて高性能な小型帯域通過フィルタ(BPF)を設計する.TE_<102>及びTE_<201>モードを持つデュアルモード共振器2つを2層に配置することにより,4段BPFを構成し,そのサイズを1つ分の共振器のサイズに抑えることが出来た.さらに,入出力間の結合および非共振モードを利用し,通過域の近傍で複数の減衰極を発生させ,急峻な減衰特性を実現した.

A novel compact quasi-millimeter-wave bandpass filter is designed by using multilayered SIW dual-mode resonators. As higher order degenerate modes, the TE_<102> and TE_<201> modes, of square SIW cavities are used, the size of these cavities are relativity large. As a consequence, the filter is easy to fabricate. On the other hand, as the dual-mode cavities are stacked into two layers, the area occupied by the four-degree filter is reduced by three-fourth. Multiple transmission zeros are obtained because of the coupling between the input and output lines of the filter, as well as the non-resonant modes in the filter. As a result, sharp skirt property of the passband is realized.
