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)

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

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!
