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。
In this paper, the combination of mode matching and multimode network is used to analyze the reflection characteristics of cone horn antenna. In the analysis process, the radiation problem of the antenna is transformed into the transmission problem of the corresponding waveguide structure, thereby avoiding the difficulty of solving the field source problem and simplifying the calculation process. The analysis of the reflection properties of the circular waveguide with a circular aperture is consistent with that obtained with the rigorous diffraction theory. The calculation of the VSWR of the cone and the comparison with the experimental data confirm the validity and accuracy of the proposed method.
