Design of an Economical Compact Combline Filter

摘要：

An economical compact narrowband bandpass combline filter with coaxial input is presented.A novel configuration using identical post with capacitance-loading is introduced. Simulated results show that with order-5 filter centered at 2.0175 GHz,return loss lower than -18 dB can be achieved over a relative bandwidth of 0.75％. Sample filter has been fabricated and tested result confirmed the concept and the simulated results,In This paper,simulated and tested results will be given to illustrate the concept.
