摘要
选择RWG和Costa基函数用矩量法分析了线面结合的天线问题,计算了月球射电仪典型天线的输入阻抗和方向图。给出了单极和双极天线的典型结果,得到了金属盒大小对结果的影响关系。对于双极天线还对比了中馈和边馈两种方式的结果。在计算中,使用了9点高斯积分法处理奇异积分,得到了较好的效果。
In this paper, the problem of junction between wire antenna and conducting board is analyzed by the moment method with. RWG and Costa basis functions. The input impedances and patterns of typical lunar radio telescope antennas are obtained, which include monopole and dipole antennas. The impact of metal case size is discussed. For dipole antennas, the results for different types of feed are contrasted. The 9 point Gauss integration is used to treat the integration singularity, which requires small memory with a high precision.
