摘　　要：自从2001年首次实现人工左手媒质以来,人们一直致力于制作大带宽、低损耗、易集成且具有左手特性的微波器件与天线.本文着重介绍两种基本的左手结构在平面微波电路中的应用,其一是左右手复合结构,其二为互补开口谐振环结构.近年来,这两种结构在微波器件及天线设计中得到广泛研究与应用.本文总结了国内外在这两个方面的研究进展,并结合我们在这方面所取得的成果,对平面左手电路的原理和应用进行了详细分析和说明.Since the artificial left-handed material was realized in 2001, it has been devoting to design left-handed microwave components and antennas with large bandwidth, low loss and high integration ability. In this paper, two kinds of left-handed structures used in microwave components and antennas are reviewed, one of which is the composite fight/left-handed structure, and the other of which is the complementary split-ring resonator structure. Both structures have been widely studied and applied in the design of microwave components and antennas. The progress of the related researches on these two structures is summarized in this paper, in addition to some of our achievements. The principles and applications of planar left-handed circuits are analyzed and demonstrated in details.
