The Design of a Dual-group Directors Yagi-Uda Antenna

双组引向八木天线的设计

Based upon the equivalence principle and surface integral equations,the exact model of the dipole antenna and Yagi-Uda antenna in the presence of the von Karman radome is established using the method of moments(MoM),respectively.

利用等效原理、表面积分方程并结合矩量法(MoM),分别对带有冯卡曼天线罩的对称半波振子和八木天线进行了严格建模分析。

A double population genetic algorithm(DPGA) combined with finite-difference time-domain(FDTD) method is introduced to optimize the element spacing and lengths of Yagi-Uda antennas.

采用双种群遗传算法(DPGA)结合时域有限差分法(FDTD)优化八木天线的单元间距和长度,以实现更优方向图。
