Abstract :
In this paper, the fast and efficient method based on MOM is proposed for the analysis antenna with bodies of revolution. The Fourier series is as the base function along the direction of revolution, the order of matrix is efficiency reduced. The FFT transform is used to avoid singularity. Take the wire antenna mounted on a finite solid conducting cylinder as an example, the impedance characteristics and radiation pattern is computation, The good agreement that numerical data obtained using above analysis are compared with those of CST soft shows the method is efficient.
