图2 (a)不同谐振环宽度w对应的S11曲线仿真（${{g}_{\text{c}}}=$0.1 mm），图中插图为${{Q}_{0}}$值和谐振频率Fr随w的变化曲线.w =1.5 mm时，谐振器${{Q}_{0}}$值最大，此时Fr = 7.2 GHz；(b)不同${{g}_{\text{c}}}$值对应的S11曲线仿真（w = 1.5 mm）.${{g}_{\text{c}}}=$0.1 mm时，谐振器耦合效果最好，图中插图为${{Q}_{0}}$值随${{g}_{\text{c}}}$的变化曲线

Fig. 2 (a) S11 curve simulation corresponding to different w values (${{g}_{\text{c}}}=$0.1 mm), the illustration in the figure shows the influence of w on ${{Q}_{0}}$and Fr. The${{Q}_{0}}$of the resonator is the maximum and Fr is 7.2 GHz when w is 1.5 mm; (b) S11 curve simulation corresponding to different ${{g}_{\text{c}}}$values (w = 1.5 mm), it would be the best coupling when${{g}_{\text{c}}}=$0.1 mm, the illustration in the figure shows the influence of${{g}_{\text{c}}}$on${{Q}_{0}}$
