摘要: 基于负折射率传输线（Epsilon Negative Transmission Line，ENG-TL）理论和开口谐振环的负磁导率特性，提出了一种加载ENG-TL结构和互补开口谐振环（Complementary Split Ring Resonators，CSRR）结构的单极子天线模型.该结构实现了单极子天线的小型化多频带.仿真和实验结果表明：所设计的单极子天线覆盖了WLAN（2.4/5.2/5.8 GHz）和WiMAX（3.5/5.8 GHz）频段.

Abstract: In this paper, a monopole antenna model with epsilon negative transmission line(ENG-TL) structure and complementary split ring resonator (CSRR) structure is proposed, which is based on the ENG-TL theory and negative magnetic permeability characteristics of the open resonant ring. This structure realizes the miniaturization and multi-band of the monopole antenna model. The simulation and experimental results show that the designed monopole antenna covers WLAN (2.4/5.2/5.8 GHz) and WIMAX (3.5/5.8 GHz) band.
