摘要

本文介绍了一种合成三元天线阵列平顶波束辐射图的新方法。目前，这是唯一一种1)给出半解析解，2)使用物理严格的天线阵列模型，3)具有简单的可行性条件，可以提前评估解的存在性的方法。该方法采用可计算、可测量的复杂有源元模式。合成图案的形状由光束的宽度和其顶部的波纹来定义。用代数公式和简单的迭代法计算了辐射单元的激励。通过算例验证了所提方法的有效性。

A Semi-Analytical Method for Synthesis of a Flat-Top Beam Radiation Pattern of Three-Element Antenna Arrays

This article describes a new method for synthesis of a flat-top beam radiation pattern of three-element antenna arrays. Currently, this is the only method that 1) gives a semi-analytical solution, 2) uses a physically rigorous model of an antenna array, and 3) has a simple feasibility condition that allows the existence of a solution to be assessed in advance. The method uses the complex active element pattern, which can be calculated or measured. The shape of the synthesized pattern is defined by the width of the beam and the ripple of its top. The excitation of the radiating elements is calculated using algebraic formulas and a simple iterative procedure. The usefulness of the proposed method has been demonstrated with the help of some examples.
