将伞形印刷振子天线等效为线振子, 用矩量法进行了分析,求得了天线的输入阻抗和E、H面方向图,在此基础上对天线的馈电巴伦和匹配电路进行了一体化优化设计。实验结果表明所设计的伞形印刷振子天线匹配良好,带宽达22.22%,比已有文献结果要宽得多,从而证明了本文分析方法的正确性,为印刷振子的设计提供了一个简单有效的方法。

The input impedance characteristics of the broadband umbrella shape printed dipole are investigated. Changed to line antenna equivalently, the printed dipole can be analyzed using the method of moment. Thus the input impedance, E plane pattern and H plane pattern of the printed dipole can be obtained. According to the input impedance, the Balun and matching circuit can be designed. The results are in agreement with the analysis results well. An effective method of analyzing and designing printed dipole is given in this paper.
