摘要：

A generic lumped-element circuit of dual-band bandstop filter (DBBSF) is proposed based oil novel composite shunt resonators, and its design method is developed with closed-form-formulas. As all example, a DBBSF with center frequencies of 1.7 and 2.3 GHz is designed and fabricated using microstrip lines. The measured frequency response agrees excellently with the theoretical predictions, validating well the proposed design theory and filter structure. (c) 2008 Wiley Periodicals, Inc.
