图1 双开口环（DSR）谐振器平面结构示意图.谐振环与阻抗匹配线间距为${{g}_{\text{c}}}$；谐振环宽度为w，开口间隙${{g}_{\text{s}}}=$0.5 mm，谐振环半径r2 = 3 mm、r3 = 3.2 mm、r4 = 4.2 mm；阻抗匹配线宽度d = 3.2 mm；谐振环左侧是一铜箔，通过调整铜箔位置可实现调谐

Fig. 1 Schematic of the DSR resonator. The distance between resonant ring and feeder line is${{g}_{\text{c}}}$, the width of the resonant ring is w, the gap of DSR is${{g}_{\text{s}}}=$0.5 mm, the radius values of the resonant ring are r2 = 3 mm, r3 = 3.2 mm, r4 = 4.2 mm, and the width of the feeder line is$d=$3.2 mm. Tuning is achieved by adjusting the position of the copper flake on the left side of the resonant ring
