Abstract

This paper presents a novel compact dual-tri bandpass microstrip filter employing meander and open stub loaded resonators. With the proposed technique, a simple transformation from dual-band to tri-band BPF is realized. A novel structure using embedded resonators is designed to generate multi-band response. The main resonators control the low-band resonant frequency, the meander resonators control the two high-band resonant frequency and the open stub resonators control the high-band resonant frequency. The meander/stub resonators are embedded into the main spiral resonators, which makes the filter compact where its size is reduced by 64% compared to traditional filters. Passbands improvements and high selectivity are realized by the short circuit stubs which generate additional transmission zeros. The proposed filter has advantages such as low insertion loss, compact size and high selectivity. The theory is validated using the commercial full-wave solver CST 2012. Finally, the proposed structure is implemented and the measurement results are found to be in good agreement with the simulation results.
