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。
Based on the technology of compound left hand and right hand transmission line, an ultra small antenna is designed. A zero order resonant antenna is obtained by adjusting the structure of the compound right and left hand transmission lines. The operating frequency of the antenna is no longer dependent on the antenna geometry but only the left hand transmission line Inductance and capacitance-related, which can greatly reduce the antenna geometry. In this paper, a small antenna is designed based on the composite left and right hand transmission line so that it can work in the ISM band to meet the requirements of wireless local area network (2.4 ~ 2.4835GHz).
