摘要： 对任意旋转平滑形导体上任意取向的线天线所辐射的扬进行探讨。采用了矩量法和傅里叶分析法,给出了导体感应电流谐量表示式,由此可求辐射场。进而以球体上任意取向赫芝振子为例求出辐射场,并与经典法公式计算结果比较,两者一致。

Abstract: Radiation field of arbitrarily oriented linear antenna overa conducting rotationary smooth body is researched.By utilizing methodsof moment and Fourier analysis,the expressions for harmonic compo-nents of induced currents on the conducting surface are given,and thenthe radiation field may be evaluated.As an example,the radiation fieldof an oblique Hertz dipole over a sphere is calculated and compared withthat obtained by classical method.Two results are identical.
