Compact Bandstop filter with improved outband character

摘要：

　　This paper presents a compact band stop filter (BSF) with multiple rejection zeros (RZs).Quasi-lumped technique is applied to the design of the proposed filter.Multiple rejection zeros are introduced by open-end stubs for high selectivity.Design equations are obtained by using a Iossless transmission line model.The calculated results show that the lower and upper rejection zeros can be easily tuned by the coupling capacitor and the open-end stubs respectively.By using the Microstrip-Coplanar-Waveguide (CPW) structure,the size of the proposed filter can be reduced to 12.Smm×9mm(i.e.,0.24 λg ×0.17 λg),whereλg denotes the guided wavelength at center frequency.
