Abstract

In this letter, a fractal structure used for the miniaturized design of microstrip bandpass filter (BPF) is presented. A new resonator called Greek cross fractal resonator (GCFR) in this paper was constructed by combining the proposed fractal structure with a traditional dual-mode meandered loop resonator. Three BPFs based on the new resonator with different orders iteration were analyzed. In addition, the mode-splitting characteristic and impact of the perturbation element on the performance of the BPFs were also investigated. The simulated results show that the new fractal resonator has a certain potential in the miniaturization design and the BPFs possess acceptable frequency characteristics. Therefore, the proposed fractal structure can be used as a candidate for miniaturization technology.
