HFSS复杂天线阵列电磁分析网络自适应信息寻找研究

摘要在对天线中存在的不均匀网格问题进行分析研究时，如果对复杂天线进行实体建模，单纯通过实体建模来进行实验的方法来分析其网格自适应信息，这会需要相当大的实验成本，而且各种细微的实际因素会影响到实验数据的测量，从而导致测量结果与实际值有较大的误差。本课题通过商业建模软件对目标天线进行建模，进而完成复杂天线线网格单元近远场划分及自适应分组，通过这种方式使实体建模带来的不必要的费用大幅的降低，在某种程度上相当大地推动了复杂天线电磁仿真技术的发展。41873

本文通过HFSS建模软件完成对天线的建模，对天线网格单元进行近远场划分以及自适应分组的内容进行探讨研究分，并加以分析。由于均匀分组的过程中会产生相当多的目标未知量，计算的内存需求会相应变大，本课题采取对目标天线不均匀剖分以及自适应分组的思想，对天线低频域的细微结构部分按低频分组的标准往下细分；其余部分不变，对天线整体按照中频域分组的方法进行分组。通过这种方法实现对目标天线低频细微部分应用MF-FMA,而剩下的部分仍采用FMM或MLFMA。

Title Complex adaptive antenna array electromagnetic analysis of network information for research

Abstract

When researching problems in non-uniform grid antenna analysis, if the entity modeling of complex antenna simply by using the method of model experiment to analyze the network adaptive information, it will cost too much and the actual measurement are susceptible to the influence of various factors, there will appear many error measurement results. This topic uses business modeling software modeling of target antenna, and then complete the complex near the far field antenna line cell pision and adaptive grouping, thus greatly reduce the unnecessary cost brought by the entity modeling, greatly promote the development of the study of complex antenna electromagnetic engineering.

This paper uses HFSS software to complete the modeling of antenna, to nearly far field antenna grid cell pision and adaptive packet, this paper discusses the content of research and analysis. Due to the homogeneous group will produce target an unknown quantity too much, the problem of large memory requirements change, this topic to the ideas of the non-uniform subpision and the adaptive grouping, the antenna electric small size part of low frequency domain down by the standard of low frequency grouping segmentation; The rest remains the same, to the whole antenna grouping grouped on intermediate frequency standard. Through this method for the application of MF-FMA, and the rest is still adopted FMM and MLFMA.
