摘　　要：采用严格的模匹配方法分析了新型双介质栅毫米波棒形全向天线的辐射特性 .结果表明 ,在辐射条件相同的情况下 ,双栅天线比单栅天线有更小的几何尺寸 .这在对系统的重量和体积有严格限制的应用场合无疑具有重要意义 .文中所得的结果与文献中相关数据的比较证明了本文分析的有效性和可靠性 .The radiation characteristics of a new millimeter-wave omnidirectional circular rod antenna with double dielectric gratins are analyzed with the rigorous mode matching method. The results indicate that under the condition of the same radiation intensity, the double grating antenna has relatively smaller dimensions than that of the single one. It is undoubtedly a great importance in the case where the limitation of the weight and volume of system is strictly required. The effectiveness and reliability of the present analysis are verified by the related results given in the literature.
