摘要
简要介绍了几何绕射理论（ＧＴＤ）和一致性绕射理论（ＵＴＤ）的基本原理。分析了圆柱缝隙共形阵天线单元间的互导纳。在主模情况下，ＧＴＤ的解和模态解具有很好的一致性。
This paper briefly introduces the basic principles of geometrical theory of diffraction(GTD)and the uniform theory of diffraction(UTD).Then using the principles,we anal-yse the mutual conductances between elements on cylindrical slot conformal array antennas.It comes to the conclusion that GTD′s solutions are approximate to the mode solutions under main mode.
