摘　　要：为研究高参数等离子体的低杂波可近性,基于HL-3装置设计了一套位于强场侧的低杂波天线。利用ALOHA代码对强场侧的天线进行模拟分析,针对只有一个单元的PAM天线,分别对其子波导数量、有源/无源子波导的高度、宽度和壁厚等参数进行模拟,得到了天线的最佳结构和尺寸。最终优化后的天线发射参数为:波谱中心的平行折射率N|为2.25,天线的反射系数小于2%,方向性系数大于0.59。A new lower hybrid antenna in HL-3 high field side(HFS)is designed to improve the accessibility of lower hybrid waves in high-performance plasma.The simulation of HFS lower hybrid antenna using ALOHA code is introduced.For PAM(passive active multifunction)antenna with one module,the number of waveguides and the active/passive waveguide’s height,width and thickness are simulated respectively,the optimized structure and dimension are obtained.The launching parameters of the finally optimized antenna are:the parallel refractive index of spectrum center N||is 2.25,the reflection coefficient is less than 2%,and the directivity is greater than 0.59.
