摘要
讨论了一致性几何绕射理论（ＵＴＤ）的适用范围，并提出其适合于源离绕射边近的处理方法。在此基础上讨论了矩形贴片天线有限接地面的影响。数值结果与已发表的文献中的实验结果符合很好。
The range of application of uniform geometrical theory of diffraction (UTD) is discussed.It is pointed out that UTD is valid when a source is near the diffraction edge.Based on the above conclusion, the effects of the finite ground plane of a rectangular patch antenna on the radiation patterns are discussed.The numerical results are in good agreement with the experimental results.
