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 compos ed of spiral resonators is proposed and this kind of lefthanded phaseshift u nits are the key components to realize lowprofile monopoles. With the help of fullwave simula tion tool, symmetrical directlyconnected cell, symmetrical indirectlyconnect ed cell and unsymmetrical indirectlyconnected cell are comparatively studied. The results indicate that the insert loss character of unsymmetrical indirectlyconnected c ell is better than that of symmetrical indirectlyconnected cell and the phase propert ies of these two units are similar in quite broad frequency band. In addition, t he lefthanded effect of the above-mentioned two units is more obvious than that of symmetrical direct lyconnected cell.

Key words: spiral resonator left handed phase shift cell low profile monopole
