Ne tür PCB var?

Can not you design your pcb design for 2.4 GHz at 5.8 GHz?

PCB FR4

Thickness = 1mm
Copper surface thickness = 35 μm

It's not a problem, dear friend.
But will it take too long?

But why do you want 5,8ghz, that's the upper limit of the band, I think you need 5.65ghz

No. It should be 5800 MHz center frequency.
It will operate between 5700 MHz and 5900 MHz.
But the center frequency will be 5.8 GHz

I'll share some pictures with you.
Pictures of pcb antennas I have built.
But the results are pretty bad.

As you can see from the analysis in the picture, the center frequency of the antenna is 5430 MHz.
Actually, I did my calculations at 5800 MHz :)
It was a pretty unsuccessful job

Measure from outer path to inner path 11,64mm
Do you think it should be 11.17mm?

Yeah, I made a copper wire antenna. But it's a tough job. And it takes a lot of time. I can not always adjust the copper wire length to the correct size.

Mate.
I made a drawing according to the measurements she gave with Solidwork.
Would you please examine it?

16mm circle diameter can not adversely affect VSWR?

Yes, I will do a simulation with this configuration ...with 0,75 not 1.5mm
Please send me the igs (iges) file from solidworks for faster simulation

I look forward to the figures you have for building your pcb.
I want to build it and test it tonight.
