PCB antenna for WIFI

Hello Guys,

I have read some docs to create wifi antenna on PBC itself.

How can I increase gain level in PCB antenna?

Only by making it less lossy with Getek or polyamide , tune the return loss with variable Foil size (trim) or design it to be more directional with gain. PCB dielectric is typically very poor tolerances unless tested for impedance control.
