摘要

本文提出了一种基于椭球体算法的Yagi-Uda天线单目标优化方法。对于目标函数未知的问题，如代表Yagi-Uda天线行为的函数，椭球体算法具有比其他优化方法更有趣的一些特征。采用矩量法(MoM)对电场积分方程(Pocklington积分方程)进行数值计算，得到天线的电磁特性。椭球优化导致天线几何结构具有比现有文献中提出的更好的指向性。

Yagi-Uda antenna optimization by elipsoid algorithm

This work presents a mono-objective optimization for a Yagi-Uda antenna applying the ellipsoid algorithm. For problems which the objective function is not known, like function that represents the Yagi-Uda antenna behavior, the ellipsoid algorithm has some features that make it more interesting compared to other optimization methods. To obtain antenna electromagnetic characteristics it is used the electric field integral equation (Pocklington integral equation) numerically evaluated by the Method of Moments (MoM). The ellipsoid optimization leads to antenna geometry with superior directivity than those presented in the available literature.
