radiation pattern of dipole using method of moments

cn anyone help me getting the radiation pattern of a dipole??I'm using method of moments.With that i got current distributions.I used piecewise sinusoidal functions.After that i've to plot the radiation pattern.I'm getting differnt value of current for same regions as i'm using the overlapping while using thepiecewise sinusoidal functions.can ny1 suggest me a solution.
Thanks in advance

Are you trying to write your own MoM code to compute this?

The easiest "solution" is to pick one of the many free MoM programs, but perhaps you are looking for something else. You have not really explained yourself too well.

If you do want a free MoM code, I personally recommend MMANA-GAL, as the limits on the free version are much larger than other free programs. You can have 8192 line segments, whereas some other programs limits you to 20 or so in the free version.
