| Abstract: | In this paper, several square open-loop resonators with transmission lines are proposed to design optimized bandpass filters. In comparison with conventional open-loop resonator bandpass filters, the proposed filter can achieve size reduction. A compact microstrip filter using one of these open-loop resonators is fabricated and measured. Simulation and measurement on the fabricated filter show high frequency selectivity and good stop-band characteristic with small dimensions. Compared with conventional filters using coupled square open loop resonators, the proposed filter has a size reduction of 30%. |
