| 摘 要： | 设计了一种简单的双面单方环结构左手材料,在4.8–5.25 GHz频率范围内该材料的等效介电常数和等效磁导率同时为负.将此单方环左手材料作为覆盖层,置于中心工作频率为5.0 GHz的微带天线之上. 仿真和实验研究表明:相对普通微带天线而言,覆层微带天线的性能得到了明显改善, E面和H面的半功率波束宽度分别收缩了25°和20°,定向性得到了提高, 5 GHz处的增益提高了3 dB, -10 dB带宽增加了600 MHz.关键词：单方环结构左手材料微带天线

| Abstract: | A simple structured left-handed metamaterials composed of single square ring cell is fabricated. Its permittivity and permeability are simultaneously negative in 4.8-5.25 GHz. A 5.0 GHz microstrip antenna is proposed, and we use this single square ring structured left-handed metamaterials (SSR-LHMs) as covering layer. Simulation and experiment results show that compared with conventional microstrip antenna, the performance of the new microstrip antenna with SSR-LHMs has been improved remarkably. The -3 dB beam of E-plane and H-plane can be reduced respectively by 25° and 20°, so the directional property of the antenna is enhanced. The gain is improved by 3dB and the -10 dB bandwidth is increased by 600 MHz. |
