| 摘 要： | 基于复合左右手传输线技术研究设计超小型的天线,通过对复合左右手传输线结构的适当调整获得一个零阶谐振天线,此时天线的工作频率不再依赖于天线的几何尺寸,而只与构成左手传输线的电感与电容相关,从而可大大降低天线的几何尺寸。文中基于复合左右手传输线设计了一款小型天线,使其可以工作在ISM频段,能够满足无线局域网(2.4~2.4835GHz)的要求。

| Abstract: | Small antenna based on composite right/left-handed（CRLH） transmission line is developed, and the zero- order resonance mode of the antenna obtained by adjusting the structure of composite right/left-handed（CRLH） transmission line. And now the operating frequency of the antenna depends no longer on the geometry of the antenna and only concerns the inductance and capacitance of the left-handed transmission line, and these could greatly reduce the geometric size of the antenna. In this paper a small antenna based on composite right/left-handed（CRLH） transmission line is proposed and designed, which could work in the ISM band, and meet the requirement of wireless local area network（2.4 GHz-2.483 5 GHz） |
