摘　　要：本文给出了抛物环面天线的参数方程和辐射场公式。利用给出的公式研究了抛物环面天线的增益和旁瓣特性。最后，对一个实际天线的方向图进行了理论计算，与测量值比较，两者吻合得很好，从而验证了理论分析和计算的正确性。In this paper,the parametric equation and radiation field formulas for a parabolic torus reflector antenna are given. The gain and radiation properties of the antenna are investigated by using the above formulas. Finally,the calculated radiation patterns of a practical antenna are given and compared with measured ones. They are in good agreement,which shows that the theoretical analysis and calculation are correct.
