An efficient hybrid method is presented to obtain the current distribution of both non-uniformly linear and planar arrays By sampling the array factor of a desired radiation pattern, the proposed method provide Fourier coefficients and uses the Least Mean Square method (LMS) to solve the system of equations in order to obtain current distribution in associate with the desired radiation pattern. Obtained side lobe level is 3 dB lower than conventional methods such as LMS method or Legendre function method.
