| 摘 要： | 本文应用几何绕射理论研究了有限结构体上天线的辐射特性，并给出了圆柱体上直立天线的计算结果。几何绕射理论是天线特性的近似计算方法，它采用了局部场原理和费马原理，将辐射总场分为直射场和绕射场两部分，便于工程计算。本文利用几何绕射场解，计算了归一化方向图，结果表明与实测很吻合。

| Abstract: | In this paper, the antenna radiation features on finite constructional bodies is studied via GTD, and the calculated result of vertical antenna on cylinder is obtained. Geometrical Theory of diffraction(GTD) is an approximate method of antenna calculation, in which the part field and fermat principle are used, and radiation field is divided into direct radiation field and diffraction field. It is easy forengineering calculation. The normalized patterns are calculated via GTD solution, the solution given in this paper agrees with measured solutions. |
