| 摘 要： | 提出了由螺旋谐振器构成的新颖非对称非直连形式左手移相单元，目前此类左手移相单元是实现低剖面单极子天线的关键器件。利用全波电磁仿真工具，对非对称非直连单元和已经提出的对称直连单元、对称非直连单元进行了比较研究。结果表明，非对称非直连单元比对称直连单元插损特性好，而且其相位特性在很宽的频带内非常相似；上述两种单元比对称直连单元表现出更明显的左手效应。

| Abstract: | A novel unsymmetrical indirectly connected left handed phase shift cell composed of spiral resonators is proposed and this kind of left handed phase shift units are the key components to realize low profile monopoles. With the help of full wave simulation tool, symmetrical directly connected cell, symmetrical indirectly connected cell and unsymmetrical indirectly connected cell are comparatively studied. The results indicate that the insert loss character of unsymmetrical indirectly connected cell is better than that of symmetrical indirectly connected cell and the phase properties of these two units are similar in quite broad frequency band. In addition, the left handed effect of the above-mentioned two units is more obvious than that of symmetrical directly connected cell. |
