摘要
Based on graphene integrated dual-mode microstrip resonators, two dual-band tunable filtering attenuators with similar performance but different structures and theories are designed in this paper. The field distribution and resonance frequencies of dual-mode microstrip resonator are analyzed, so that the influence of graphene on different resonant modes can be confirmed. Then, two dynamically tunable dual-band filtering attenuators are designed. By using different design concepts and selecting appropriate loading positions of graphene, two different filtering attenuators which can achieve controllable attenuation from 1.5 dB to 7.1 dB and 1.7 dB to 7.6 dB at the first or the second band can be obtained. Last but not least, the attenuations of this two passband can be controlled independently.
