本文简要地回顾了传统上对天线的要求,并以实例说明随着近代科学技术发展的需要,天线波束的相位特性应该引起重视和研究,在此背景下本文试图将天线波束相位和孔径电流分布等有关问题系统化,在前人工作的基础上,总结并讨论了关于相位参考点、不同相位参考点的天线方向图的变换关系、方向图的零点电平和相邻波束间的相位差,线阵电流分布的分解;提出并从理论上证明了天线同相波束的普遍条件和连续线阵的对称波束条件。归纳为几个定理,并将这些论述统称为天线波束相位理论。
In this paper, we briefly review the traditional antenna requirements and illustrate that with the development of modern science and technology, the phase characteristics of the antenna beam should be emphasized and studied. In this context, the antenna beam phase and aperture current distribution Based on the work of predecessors, this paper summarizes and discusses the transformation of the antenna pattern of phase reference points and reference points with different phases, the zero level of the pattern and the phase difference between adjacent beams, and the line And the decomposition of the array current distribution. The universal conditions of the in-phase beams and the symmetric beams of the continuous beams are proposed and theoretically proved. Summarized into several theorems, and these discussions collectively referred to as antenna beam phase theory.
