谱域法在微波天线中的应用研究

简单介绍了谱域法产生的背景。应用领域和发展前景，对天线中所到的平面波谱理论进行了较详尽的介绍，并应用此理论计算了同轴双扼流环多模喇叭天线的辐射方向图，与测量结果相符，证明了本文分析方法的正克性和有效性。

Applying Research of Spectral-Domain Approach in Microwave Antenna

This paper simply introduces the production background, applying domain and development prospect of Spectral-Domain approach. Plane wave spectrum as the basis knowledge of antenna research is introduced in detail. As an example, the radiated patterns of the coaxial multi-mode horn of two chokes are calculated and the results are agreed with the measured results. It shows that the analysis method in the paper is proper and effective.
