Directional antenna 2.4 Ghz band of the FA20

33 posts in this topic

I have tried many times to make a simulation at this antenna but I was never satisfied with its results.

So I made a change to it, and I got some good results, especially with regard to the frequency bandwidth

Ziroc I can only say again that you are really talented and that looks so cool. If I could do something which was half as good I would be so happy.

Fa20 Patches doesn't like DIRECTORS...reactivity and diagram goes "ape shit crazy"
