基于一种新型超材料单元———非对称耦合螺旋谐振器,提出了基于该单元的顺序旋转馈电网络设计方案.由于螺旋谐振器的内卷几何特性,非对称耦合螺旋谐振器尺寸非常紧凑.同时,研究发现,该单元的-90°相移频率大致与通带中心频率对应,对于设计正交相移微波器件具有重要价值.由于非对称耦合螺旋谐振器的上述优点,提出的馈电网络结构具有小型化和调试简单等优点.测试结果表明,该馈电网络能够较好地满足顺序旋转馈电的要求.

@@@@A novel sequentially rotation feed network based on the novel metamaterials cells,or asymmetrical coupled-spirals resonators(ACSR)is proposed in this paper. Due to the intrinsic convoluted geometry of spiral resonator,the dimension of ACSR is extremely compact. Simultaneously,it is demonstrated that ASSR exhibits the bandpass property and the frequency point with -90 degree phase shift just right falls in the given pass-band. This exotic property is quite valuable to design the quadrature phase shift microwave components. Utiliz-ing the abovementioned merits of ACSR,the proposed feed network has the advantages of compact dimension and easy adjustment. The measured results indicate that the proposed feed network can satisfy the requirements of sequentially rotation technology.
