摘　　要：本文基于色散稳定,频带宽的左手介质LHM结构单元,设计了一种左手材料,用作天线的覆盖层,利用左手材料的平板聚焦特性,实现提高天线的增益,减小天线波瓣。经过电磁仿真的结果表明使用左手材料覆盖层后天线波瓣减小了12度,增益提高了1.2dBi。In this paper, a left-handed material designed for antenna cover, use the left-focusing properties of fiat-panel materials, improve implementation of the gain of the antenna, reducing antenna lobe. After the electromagnetic simulation, results show that by use of the left hand materials as cover, the antenna reduces the lobe 12, the gain increased 1.2dBi.
