摘　　要：本文以周期结构理论为基础,提出了一种新型的基于屏蔽带状线的周期结构,利用传输矩阵和BLOCK阻抗相结合的方法证明该结构在特定频段内传播常数和BLOCK阻抗实部同时为负,具有左手特性,在此基础上分析了该结构的传输特性。结果表明,所设计的周期结构左手带宽超过30%,同时内导体厚度较大,可用于高功率传输。A kind of periodic structure using shielded stripline is proposed, which is based on the theory of periodic structure. The propagation constant and block impedance are proved to be negative simultaneously at certain frequency range, and the structure is proved to be LHTL. The transmission character is analyzed according to LHTL （Left-Handed Transmission Line） theory. Statistical results show the structure exhibits left-handed behavior over 30% bandwidth. At the same time, the inner-conductor is thick, so the structure can be used to transmit more power.
