摘　　要：本文用一种新的思路来分析H(01)或E(01)波激励下圆形介质棒天线的反射特性。与常规的从场源关系出发来分析天线问题不同，本文的方法从求解介质波导结构的色散特性入手，从散射的角度将天线辐射问题转化为表面波和空间波的传输问题，从而使分析过程得到了很大的简化。A new idea is proposed in this paper to analyze the reflection characteristics ofcircular dielectric rod antenna excited by H01 or E01 mode- Unlike the conventional method oftreating the radiation as a ' source-field' problem, in the present approach, the dispersioncharacteristics of dielectric guided-wave structures are analyzed first, and then the radiationproblem which creates the reflection of the antenna is transferred to the propagation of thesurfacewaves and the space waves from the viewpoint of scattering, so that the analysis is greatlysimplified.
