d'avoir répondu à mon post, c'est que l'on peut avoir un circuit explicatif qui me permettra d'implémenter mon antenne avec une impédance coaxiale de 75 ohms.
Merci

Samir,, wait until I do a simulation for the 75 Ohm coaxial cable..!!!

[Admin 2545]

These are the dimensions for the 2.4GHz Bester antenna

Salem thanks for this 2.4ghz wifi antenna circuit i will make and then test

Salem, let me ask you this question about the design and modification of this 4G LTE 1800MHz antenna model, the diagram is attached, Question 1; do we have new model for 75 ohm coaxial cable

Yours sincerely

[Admin 2545]

 Samir, only English is spoken here ... !!!

,,,for 75 ohm cable the only difference is h1 and h2...!!!

Admin, thanks for reminding me about using the English language on the forum. for the antenna, I will carry the corrections on my antenna at the level of the reflector and the vibrator Sincerely yours

Hello Admin, 

I would like use this antenna for 4G LTE (1800 Mhz) witha 75ohm cable. If I want to add the 2nd feed, should I put it at 120° as always? 

Thank you

Hello Admin, 

Can I use this antenna with a parabolic dish for 4G LTE (1800Mhz)? Is it the best solution or do you have other improvements? 

Thank you

[Admin 2545]

Of course...!!!

If I want put the 2nd feed. It should be placed at 120°. Correct?

[Admin 2545]

,,,yes...

Can I get dual band antenna ...???

[Admin 2545]

,,, such as dual band,,,??, maybe, cross polarization...!!!

hi admin can this use a 75 ohm cable or do you have to change the distance

[Admin 2545]

,,, for the impedance of 75 Ohm, the distance of 7 mm must be modified...!!!

[Dedewe 1]

I have 75 ohm material can you give a schematic? let's be clear thanks in advance.. healthy long life for admin

[Admin 2545]

,,,okay, I will try...for the frequency of 1800 MHz...??/

[Dedewe 1]

Thank you for your time and everything

[Dedewe 1]

[Admin 2545]

Dedewe,how would that be...

[Dedewe 1]

and I will try to apply it in the real world thank you admin and God who will repay your kindness

How about mimo system. The. Decoupling. Of. 2 ports 120 degree.  Is it. Good. ?  I want   to  see the s1s2. !!? Thanks by advance jomy 

[Admin 2545]

,,,it is possible, but the isolation between the ports is not good..!!

Can I build this antenna with galvanized steel sheet? Does it work or it Must  be double sided pcb?
