Will this happen?

16mm circle diameter can not adversely affect VSWR?

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

OK. I will make a Quick Draw and share it with you

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.

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

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

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

Reflective reflector panel size 51x51mm Bi-quad height = 17mm Bi-quad Width = 33mm

Can not you design your pcb design for 2.4 GHz at 5.8 GHz? PCB FR4 Thickness = 1mm Copper surface thickness = 35 μm

FR41mm pcb. Frequency = 5800 MHz

100x100 mm becomes a very large antenna. I'm trying to make a bi-quad with 50x50mm panel size. You can look at the pictures of the sample work I've done. My handheld antennas were quite successful. But it takes a lot of time. I also have to do more than one experiment to get the right frequency and vswr value.

I like your design so much but very much. This design works. I use RF Explorer Analyzer to measure antennas. If the design in this picture works, I would definitely like to build and test it at 5800 MHz frekans

I have built various pcb baklava with theoretical calculations for 5800 MHz. But I could not catch the right frequency. For example, the pcb in this picture was measured as baklava 5560 MHz frekanssta 1.03 vswr

An antenna with 4 panels is quite large.

My dear brother. I'm really grateful to you for that. There are some studies I have done, but they are built entirely with theoretical calculations and do not work with the right frekans

Hello there. Congratulations on your work. As amateur I do drone drill with FPV systems. One of the biggest problems with this hobby is the antenna. I am over biquad antennae. And I want to make one biquad antenna for 5.8 GHz. This pcb design was really amazing. I congratulate you. Can you make a biquad antenna for 5800 MHz? I am grateful to you. If you share the measurements, I can easily build it. If the PCB thickness is 1mm, it will be lighter.
