Abstract

A new method which can be easily implemented on PC is presented for analyzing the characteristics of cylindrically conformal microstrip antennas.Based on the method of moments (MOM)

the fast oscillatory and slowly convergent parts of the generalized impedance matrix and voltage vector elements are extracted

then these elements are cast into closed-forms by using the nonlinear approximation.By using this method

the computational efficiency is improved dramatically.Compared with the published results in the corresponding references

the correctness and high efficiency of this method are verified.
