Antenna help
(OP)
Hi,
I'm new in electronic circuit. I'm working with NEC code to figure out how to analysis antenna. I want some suggestions from you guys where I can start with some simple designe of antenna that I can understand how it works and anaylses? Another question is what is the different if I exicte the antenna with a rectangular pulse, a sinusoidal, another shape of pulse? Where can I find this information?
Thanks,
Mica

Any other waveform is broadband.

Thanks,how can I modelling this? I using NEC code and I a saw something in the moldelling like excitation "EX" the antenna? Where I can find some complet examples using this code?
Thanks again,
Mica

It has a nice user interface that makes it perfectly simple to input an antenna geometry, visualize the antenna, and then run the NEC. The EZNEC demo has a 20 element limit, but that is more than enough for a simple dipole. Once you see what is going on, then you can use other NEC software that is more powerful, but still freeware. Or you could buy the full-up EZNEC...
I don't know much about 'excitation'. I just used it to check several frequencies one at a time.
