Abstract

Simple bandstop filters (BSF) are introduced in this article. The filters consist of one spurline and a pair of cross-junction open stubs. This spurline exhibits bandstop characteristics at a resonant frequency, which can be explained and modeled by one LCR-resonator The proposed BSF was designed and measured. The experimental results verify the design method and circuit modeling. Additionally, this BSF is compact and its total length is equal to γg/6. [ABSTRACT FROM AUTHOR]
