Very cool. Thank you so much master Jomy.
-
please can you give me the dimensions?

What if it was made using a thin sheet of aluminum?

What make it electric or magnetic is the field orientation Vertical or Horizontal and their LENGTH
Thank you very much Clanon

Is this type of antenna body connected to the reflector?

How to determine the distance between the biquad antenna and the aluminum sheet? Or maybe you can help master?

These are the measurements I got.

Okay. I will try to give the size in the picture. It might take some time.

I have tried to connect this antenna to a 2.4 Ghz wifi router. Antenna works fine. Can master Joymi simulate this antenna for 2.4 Ghz frequency, and how many dbi gain is obtained? Thank you in advance.

Sorry. Yes, the dimensions are the same. Right now in my country there is a lot of talk about the Catherine antenna. Looks very interesting in the attachment. To maximize the performance of this antenna is it enough to add a 120 mm reflector?

Hi admins. I'm interested in this antenna. Can I get the detailed size?
Can this antenna also work in the 3850 to 4080 Mhz frequency? -

You just attached the aluminium pieces by coper wire. And you solder the coper wire .
So the aluminium pieces are attached but not soldered .
Anyway you are welcome bro and have good luck.
Thank you. Maybe that's a more appropriate name.

As long the CONTACT is good , all ok.
At each plate connection, I put a little wedge which I glued on both sides. So the connection remains secure.

PS: is that a SIGN or a LICENSE PLATE...
If it was made a little neater, would it still affect the resonance? That's right, the material I use is the vehicle number plate / License Plate.

To conclude from the image above, each joint I'm about to solder looks like a small coil of copper wire. The key to making soldering on aluminum easier is the winding of the copper wire. I took this copper wire from a piece of LAN cable. Then, the two plates to be joined, I made holes with a diameter of 1 mm on both sides, then the two holes were joined with a copper wire coil, wrapped as tightly as possible, then just glued the tin with solder on the front and back. I think this is the easiest way to do it.

Thank you very much Master Jomy for allowing me to rejoin. And it has helped restore my membership. I really like this forum.

try using the SMA connector.
