摘　　要：提出利用左手材料的相位超前特性作为相位补偿器,调整传输线相位分布,并与右手材料相结合构成左右手传输线,用于为直线天线阵馈电,实现不同的天线馈电条件,达到不同的天线辐射特性。分析了无耗级联左右手传输线模型的相位特性,建立了基于左右手传输线的直线天线阵模型,对天线阵方向特性进行了仿真。结果表明,文中设计的天线性能明显优于传统直线天线阵。Phase compensater used positive phase delay of the left-handed materials is presented for adjusting the phase distribution of left-handed transmission line, and this transmission line will be also consist of right-handed materials, for feeding of Linear antenna array, then realize different feeding conditions and achieve different radition characteristics. Phase characteristics of right/ left-handed transmission line model which is unloss in series was analyzed, based on it, linear antenna array model was also estab-lished, at last analyze direction characteristics of this model. The result show that the performance of this antenna is absolutely better than ordinary antenna.
