Current distribution of wire antennas is studied by using wavelet method of moment, and its character is verified by examples. Firstly, the matrix equations are obtained by moment method, then the basis function and weight function in moment method are replaced by wavelet basis function for the fast calculation of current distribution. The expriment results show that the computational cornplexity of this algorithm is decreased correspondingly and computer memory is saved, And therefore, the effectiveness of this method on current equation is confirmed.
