Antennas Simulators help

Hi everyone,

I wish someone advise me a antenna software simulation that was efficient and free! i have:

- Mstrip40
- Feko lite
- Sonnet lite
- CST microwave studio
- Zeland

Have any one work with some of the list? what do you think?

Thanks!

Best regards,

I recommend you to use CST Microwave Studio but its very expensive for licencing

Can you recommend me a free licencing software?

4nec2 antenna modeler and optimizer

I would like a simulator for microstrip antennas! and i would like to have radiation pattern, current distribution, etc simulated.
I worked with 4nec2 to simulate a panel antenna, but i'm not sure if i could the same with microstrip!

Thanks for your help and will keep waiting for suggestions.
