| 摘 要： | 在圆柱面上进行一维菲涅尔区相位修正结构设计，可以构成一类新型的点源馈电透镜天线。本文利用矢量场绕射理论研究菲涅尔区修正圆柱面天线的辐射特性，并进一步分析馈源阵列作用下的辐射性能。文中天线远场方向图的计算结果与有关文献中的结果吻合。

| Abstract: | The one-dimensional Fresnel zone phase correcting principle can be applied in a cylindrical surface to constructed a new type of point source feeding lens antenna. The vector diffraction method is surface to constructed a new type of point source feeding lens antenna. The vector diffraction method is used to study the radiation characteristics of this new lens antenna feeding by dipole feed at the cyliner center and feeds array position along the cylinder z axis. Comparison of the results with the other articles'shows the validity of the theoretical analysis. |
