Hi hoke!

It is so simple. There are two basic way to do it.

1) If you know the analytic formula you may use "polar" instruction to plot the pattern in polar coordinate. Of course you have to change the Electric or Magnetic Components into Polar coordinate.

2) If you don't have any analytic formula you may use different numeric methods like: MoM, FEM, FDM, ... which help you obtain the fields in a difinite space during a difinite time. After that you may use the same structure; discused before; to plot the pattern.

Note: You can draw a 2-D Pattern by using "polar" instructor, however, you can plot a 3-D Pattern too. in that case you can use "mesh" instructor. But remember that the coordinate is cartesian.

I can send you some Examples about Hertz Dipole, if you would like.

Thanks!
