To:sergio mariotti,
Can you give me further excuse about ""current" sensitive"? or give me some examples about that.
Thanks!

To:Vaga_BOnd,
Thank you for your reply.
Now I can use GA method in 4NEC2 to simulate simple examples.
But all the parameters of GA (such as select,cross,mute and other parameter) I choose default setup.Thus this may limit my furthur improvement to GA method.In order to grasp GA...
broadband matching
Dear AmirMohammad,
Thank you for your introduction about a book named "solid state microwave amplifier design" written by T.T.Ha, although I cannot find this book.
Can you send an ebook of that one? My email:bg_islang@sohu.com.
Thanks again!

4nec2 optimizer
Hello,everyone.
How to optimize VSWR of a broad band antenna using 4NEC2?
And how to set the optimized algorithm "genetic algorithm" in 4NEC2?
Can you give me some examples to use 4nec2 with optimizer.
Thanks a lot!
I followed the tutorial,But I did not add the "Add voltage source" yet,that is,new source-object is not displayed.Can you tell me why? Thanks a lot!
Added after 2 hours 20 minutes:
Dear VSWR,
I have another question.When I run 4nec2,jump the windows that show "Error or warnings...

I am sorry for my late reply and I have no articles about RFM.Here I just have a book in which there is a...
tda6020a
Hello,everyone
Can you have seen this shortwave broadband vertical antenna TDA6020A?Its frequency range is from 2MHz to 30MHz,just using an network with transmission lines to reach the matching .And I heard that this antenna is an transmitter antenna ,which may not be a loaded...
pi network matching s11
There are many methods for broadband match,such as RFM.Recently I have been designed an matching network with that method.But I must say that we cannot get very satisfying results ,which depends on the impendance data.
BTW,cooleyn,can you tell me what is Genesys...
Re: Need Help
Hi,Rayfeko
I want to optimize antenna the VSWR and efficiency over a wide frequency range.How to program the *.opt file and *.pre file.Can you give me some examples.
Thank you!
