摘要
本文用模匹配和多模网络相结合的方法对圆锥喇叭天线的反射特性进行了分析。在分析过程中,将天线的辐射问题转化为相应波导结构的传输问题,从而避免了求解场源问题的困难;并使计算过程得到了简化。对开口圆波导反射特性的分析得到了与用严格衍射理论所得的一致的结果,通过对圆锥喇叭驻波比的计算以及与实验数据的比较,证实了本文方法的有效性和精确性。
The reflection characteristics of conical horn antenna are investigated by a new method which combines rigorous mode-matching approach with the multimode network theory.The radiation problem is transformed into a transmission problem of the corresponding waveguide structure to avoid the difficulty of the field source problem which is met in the traditional analysis. As a result, the calculation procedure is greatly simplified. Accordant results with those calculated by rigorous diffraction theory are obtained in the analysis for the reflection characteristics of opened circular waveguide. The validity and accuracy of the present method is also verified by comparison of the calculated and the experiment results of VSWR for the conical horn antennas.
