Novel Sext-Band Band-Pass Filter with Non-Coupled Structure Based on Multi-Shorted-Stub Resonators

Résumé

In this paper, we present a simple way to design sext-band band-pass filter based on multi-shorted-stub resonators. Each sext-band resonator consists in the parallel association of five stepped-impedance resonators in a noncoupled structure and allows the control of transmission zeros and bandwidths. A second-order sext-band band-pass filter is synthesized and realized in microstrip technology, the final circuit successfully integrating five stubs per resonators into a single planar circuit. Compared with coupled structures, the solution proposed here can achieve good in-band responses, band-to-band isolation with a simple design procedure. It also needs less optimization. All of these merits make this filter an attractive solution for multi-band wireless communication systems.
