Directional antenna 2.4 Ghz band of the FA20

[Admin 2545]

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

,,,otherwise constructive solutions...

,,, with round patches and box reflector...

,,, with rectangular patches and box reflector...

found on the net.. simply to build

 

[Admin 2545]

Bejo, yes I know it....!!!

But can you still show where you found that...???!!!

i know...my setting for the solver and or mi discrete port location must be REALLY OFF...

 

(closer to 0 db...i know)

 

[Admin 2545]

,,, and that's what you think... ???

my DIY 2,4ghz antenna, not test yet

[Admin 2545]

,,,good, these are the results of your antenna...

nice  design and  high GAIN    THANKS

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.

jomy It's possible to add  add  rectangular directors to the half  Fa 20 get more gain close to the FA20  at least get smaller antenna ?   

[clanon 246]

Lan23 guys  tried that...(i did )

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

this is the best i could do...16 dbi on 6 or 8 patches (20 cm by 18)

quarter FA20

I think,only like this...

,,, here on the forum, I have such an antenna...!!!

Alot of loss ! It's just 17.5 DBI I think 3/4 Fa 20  it's better but I don't have the right dimensions of it

[clanon 246]

which one the 8 patches (16db without flaps) or the 6 patches , you need...?

I would like to try the both (6 and 8 patches) thanks by advance clanon

 Can FA 16 reach 17:DBI ?  It's easier to build ...?

nope , you need at least 6 patches and flaps...for that

 

[Hamza 43]

It's Ok  I don't have problem with the flaps 

[Admin 2545]

This works too....
