It must be pretty good. And the size should be max 12x12 cm

Yes, but it must be done in this form on PCB

if we have, in Uzbekistan, will be a lot of drones, I'll do the same.

Jomy, I wish you, that your drone a lot and a lot, a long long time and flew in the sky. Then you will upload video footage from your drone.

Thank you, but you know ,this will be and because  of you...!!!

It looks great.
2420 MHz and 5775 MHz.
I can think of it as a metal with a laser.
If you can give me the relevant files I can cut with metal laser cutting.

Please tell me what materials I need to use

I think that better is galvanized or brown sheet

But why do not you want to try with PCB..??

Efendi, the antennas can be placed around the helices ... ??

I tried to check this antenna and here are the results

These are the results for the original dimensions.

And these are the results after changing the size of the patch

The enclosed dimensions are valid

But I think that this antenna is more efficient...

I am wanting to make a CP patch antenna for 1.3GHz, but am struggling to find a design with dimensions online.

I did a simulation of this antenna but with an elliptical cut in the patch, which provides a wider bandwidth

and for the 2.4GHz frequency

Another type of 1280MHz patch antenna

And this represents an improvement of the antenna

This antenna has a wider bandwidth

Hmm, that design looks easy and simple to make. 
Already ordered 4 Hole SMA jack with long center pin (17mm).
when i get it will try this design. 
But try to make it on 1mm FR4 - i got it few square meters :)
I suppose that it will resonate little bit higher.

ok, made it with eliptical cut. 1mm FR4

But first one (white) performs better. 
First one has best vswr 1.23, second one best 1.7. 
On second i've printed thin enclosure (about 2mm). Is that possible that PLA has such big impact on antenna performance.

I am going to try to do a simulation, it might be that the ellipse has other dimensions for this antenna

What thickness of PCB did you choose?

I think this type of antenna is better
