The axially arrayed helix antenna was analyzed with moment method and its current distribution and radiation pattern were studied.The principle of wavelet-moment method was described on the basis of moment method and wavelet analysis.The wavelet-moment method's advantage in computing time over moment method was discussed.The dense impedance matrix was transferred into a rarefied one with discrete wavelet transform method
and the current distribution of the antenna was calculated.It was proved that the application of wavelet-moment method could remarkably reduce the computing time and ensure the accuracy of the calculation results.
