基于左手材料的微带贴片天线

An microstrip patch antenna based on left-handed material

为实现微带天线的小型化,提出了一种基于左手材料的微带贴片天线。该天线在普通贴片天线底板上加载左手结构,利用左手材料的相位补偿特性,突破了传统微带天线的半波长限制,实现了微带天线的小型化设计。利用电磁仿真和实验分析了天线的性能,实验结果表明,加载左手材料结构的微带贴片天线的电性能优于传统贴片天线,且尺寸仅为传统天线的67.5%。

In order to achieve the miniaturization of the microstrip antenna,a novel miniaturized microstrip patch antenna based on left-handed material is proposed.The antenna is composed of a conventional patch antenna with left-handed structure.Base on the phase compensation properties of left-handed materials,the half wavelength limit of the traditional microstrip antenna is broken through,and the miniaturization design of microstrip antenna is realized.The performance of the antenna is analyzed by electromagnetic simulation and experiment,the experimental results show that the electric performance of the proposed antenna is better than the conventional patch antenna,and the proposed antenna size is only 67.5% of the conventional antenna.
