内容简介：开环谐振器阵列由于结构庞大，难以实现小型化，而逆开环谐振器则由于刻蚀在接地板上，容易对微波电路中其他部件造成干扰．针对上述问题，提出了一种新型双层介质复合左右手传输线结构，并提取了其等效相对介电常数和等效相对磁导率，然后分析了新结构的尺寸参数对其传输特性的影响程度，最后将一种新型Minkowski分形曲线应用于该结构，设计和制作了两款双频滤波器，验证了该复合左右手传输线的双频特性．
Abstract：Split ring resonator arrays are difficult to achieve miniaturization because of their big sizes, while complementary split ring resonators are easy to damage the other parts of the microwave circuit because it is etched on the ground layer. In order to solve these problems, a novel double-layer dielectric composite fight/left-handed transmission line structure is proposed and its equivalent relative permittivity and permeability are calculated. Then the influence of dimension parameters of this novel structure on transmission characteristics is analyzed. Finally two dual-band bandpass filters are designed and fabricaled by applying a new Minkowski fractal curve to this structure, and meanwhile the dual-band characteristic of this composite right/left transmission line is demonstrated.
