摘要
本文利用物理光学法导出了抛物环面天线的交叉极化辐射场公式,并用其对该天线的交叉极化特性进行了深入的研究,得出了一些有意义的结论和数值结果,为这种天线实现低交叉极化性能奠定了理论基础。
The cross polarization radiation field formulas for a parabolic torus reflector are derived using physical optics in this paper. The cross polarization properties of the torus antenna are deeply investigated with these formulas. Some significant conclusions and numerical results are obtained, which lay a theoretical foundation for this type of antenna realizing the low cross polarization property.
