[efeksk 22]

But it's pretty big

This is a great man

How great you want it,,,???

[efeksk 22]

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

[Admin 2545]

Would you like that ... ??

 

[efeksk 22]

ooowww. yessssss

[Admin 2545]

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

 

,,on PCB plate....

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

[Admin 2545]

I think that better is galvanized or brown sheet

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

[Admin 2545]

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

A new 5,8ghz simple antenna model with patches (r + p1 + p2)

 

[Admin 2545]

And a simple variant for the 2,442GHz antenna

[Admin 2545]

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

[Admin 2545]

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

Skycon Kft Antenna

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

 

 

[Admin 2545]

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.

 

[Admin 2545]

for 1.3GHz it is recommended to use elliptical cut

 

[antenna_kid 13]

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.
 

[Admin 2545]

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?

[Admin 2545]

I think this type of antenna is better

Double plated PCB

[Admin 2545]

,,,a simple sloted patch antenna for 5,8MHz

dimensions = 4,5x45x45mm

constructive details

 

on feed point,use this type of connector
