摘　　要：混合左右手传输线是一种应用电路实现的新型人工电磁媒质,具有很多新颖的特性.而基片集成波导作为一种新型传输线具有高Q值和低辐射,在毫米波应用中有很大潜力.本文提出了一种把混合左右手传输线结构和基片集成波导结合的方法,并且研究这种结构在频扫天线中的应用.全波仿真结果验证了所提方法的有效性.The composite right/left handed（CRLH）transmission-line structure is a sort of metamaterial realized by circuits, which can provide some new characteristics. Meanwhile the substrate integrated waveguide （SIW） is a new transmission line with high Q-factor and low interference, which has attractive applications in millimeter waves. In this paper, we present a new structure which combines CRLH and SIW together. Using such a structure, we study the realization of compact frequency- sweeping antennas. Full-wave simulation results show the validity of the proposed antennas.
