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F_r随w的变化曲线.w =1.5 mm时，谐振器 ${{Q}_{0}}$ 值最大，此时F_r = 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 F_r. The ${{Q}_{0}}$ of the resonator is the maximum and F_r 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 ${{Q}_{0}}$
