Dipole

[Mica188]

Hi,

If I have a dipole (horizotal or vertical), the radiation pattern is independant in phi angle but if my dipole is in a direction (i,j,k), this will dependant on phi angle? If so, what is the complet formula for this?

Thanks,

Mica

"...what is the complete formula?"

NEC (numerical electromagnetic code)

Download a free version (EZNEC is one, there are others), bang in a dipole, and run.

Is it possible to have analytical? I don't need to resolve it but just present the complet formula. The purpose of this is to introduce the NEC. I want to explain that analytical is hard to resolve so, we can resolve by numerical. So, why I need the formula.

Thanks for your help,

Mica

While awaiting a better answer than I can offer, here's an amusing little Java applet on the same subject:
