摘　　要：提出了一种基于八边形单开口谐振环(Split Single-Ring Resonator,SSRR)结构的左手材料,在6.7~11.5 GHz工作频段内该材料的等效磁导率和介电常数均为负值。利用左手材料的平板聚焦特性,将该结构的左手材料作为覆盖层置于中心工作频率为11.4GHz的微带天线上方,以提高天线的定向辐射能力。研究结果表明,加载左手材料覆盖层后微带天线E面和H面的主瓣半功率波束宽度(HPBW)分别缩减了37°、41°,增益提高了2.9d B。A left-handed material based on an octagonal split single-ring resonator structure is proposed. Its effective permeability and effective permittivity are simultaneously negative in 6. 7~ 11. 5 GHz. By using the flat-panel focusing characteristics of the left-handed material,the structure is placed on the top of the microstrip antenna with 11. 4 GHz center frequency to improve the directional radiation capability of the antenna. The research results show that the main half-power beam width（ HPBW） in the E-plane and the H-plane of the microstrip antenna can be reduced by 37°and 41°,and the gain increases 2. 9 d B after uploading the left-hand material.
