摘　　要：本文首先给出了抛物环面天线的辐射场公式,然后利用给出的公式设计和研制出一个90°角域的五波束抛物环面天线,并示出了该天线五个波束的测试方向图和中心波束的计算方向图,计算值和测量值吻合很好。最后,还介绍了中心波束和边缘波束的增益测量值。The radiation field formulas are given for a parabolic torus reflector antenna. A five-beam parabolic torus antenna with 90?azimuth coverage has been designed and developed. An experimental radiation pattern of these five beams and theoretical patterns of the central beam of the antenna are also given. Comparison between calculated and measured patterns shows they are in good agreement. Finally, the measured gain data for the central beam and the edge beam are presented.
