,,, it is enough for us, details ...!1!

8 dBi patch with matching to 50 Ohm

on the upper side of the cross transformed (100 Ohm lambda/4) to 200 Ohm to get back to 50 Ohm matching 

The cut in the patch element is for correct placement (avoid wrong rotation)

,,, when I say details, I mean dimensions.....!!!!

,,,this is patch-antenna....

 I would be interested in the connection between the 4 patches...!!!

how much is this? ,, 10x10mm ...?

,,, and patch has no reflector...???

[swarg_eu 43]

15x15mm , the arm is also plated edge at the end

[Admin 2545]

,,,like this...???,,,one patch...

[swarg_eu 43]

yes

[Admin 2545]

,,, there may be other dimensions for the 5.8GHz antenna...!!!

Is the bottom of the patch only GND in the smal part like in the figure ?

Extend the GND to the edges of the PCB

[Admin 2545]

Yes, you are right..!!

,,,it need pins between the two GNDs of the PCB"s with transmission lines  ...!!!

Hello!

Friends, are there any good patch antenna options for DJI systems? I watched the Lumenier AXII HD antenna tests. But the price of this option is very high here in Russia. Any good homemade options? I would be grateful if there is an option immediately ready-made gerber. Thanks!

[swisusto 0]

Yes ... have you got a gerber file to make this?

[Admin 2545]

,,,swisusto,these are the files you requested....

5,777ghz.gbr
