斜极化电扫天线阵阵元之间的动态隔离度

内容简介：借助感应电动势法,给出了空间两个不同馈电点位置,任意电流指向,不等长细对称振子自、互阻抗的计算公式。进而,根据自、互阻抗与S参数的关系,计算了M条线阵,每条线阵含N个阵元之任意两个斜极化阵元间的传输系数。最后,得到了两个斜极化电扫描天线阵间的动态隔离度表示式。文末,以3个实例揭示了同极化和异极化天线阵之间隔离度与波束扫描角或下倾角的动态关系。

Abstract：By means of induced electromotive force.The self and mutual impedance calculation formulas between two variable length symmetrical thin dipoles with arbitrary space feeding point positions,arbitrary directions of current are given in this paper.Then according to relation between impedance and S-parameter,transfer coefficients between arbitrary two inclined polarization array elements in a M×N array are calculated.Expressions on dynamic isolation between two inclined polarization scanning arrays are derived.Finally,3 samples are used to indicate the dynamic relation between various polarization dipoles with beam scanning angle or downward inclination.
