anybody can tell me how to denot the self and mutual impedances of radiating elements?I want to simulate the lof periodic dipole antenna in matlab.thanks!
You may try superNEC. It is a matlab interface MOM based on NEC code. **broken link removed**
There is a Yagi antenna example in the manual. you may modify it. You can try it for free for 30 days, I think
To simulate LPDA, this is same with yagi antenna (non folded),
But all element is driven and is connected by transmission link with cross link connection.
The transmission line have impedance can build with two parallel boom.
Check the following website: **broken link removed**
For all the source codes for "Antenna and EM modeling with Matlab" which is really really a great book in my personal opinion.
Hope this helps.
