摘　　要：在中国聚变工程实验堆(CFETR)螺旋波的设计参数下,提出一种多阵列行波天线用于螺旋波电流驱动的方案。利用电磁仿真软件CST对三维天线的参考模型进行了仿真,结果表明,在50MHz带宽内,天线电压驻波比<1.2,且天线阵列激发的k谱具有很好的定域性,有利于提高天线的电流驱动效率。A travelling wave antenna(TWA) has been proposed for helicon wave current drive under China fusion engineering test reactor(CFETR) physical design parameters. Using the commercial software package CST, the antenna model is simulated. The results show that the voltage standing wave ratio(VSWR) of antenna is less than 1.2 in 50 MHz bandwidth and the k-spectrum excited by antenna array is well localized, which is in favor of enhancing the efficiency of current driving.
