WiFi PCB antenna for Wireless Shell

Hi,
Does anyone have any references or ideas on how to make a WiFi Antenna on a PCB that works with Wireless Shell?
The Shell does have an connection for UFN with a matching network but this is an additional cost, and i don’t need any range…just 20-30cm, and there is also a pin “ANT”.
Its not clear from Schematics what the termination is on this pin.
Will appreciate any suggestions…

The pin labled ANT is the same as the ufl connector

Hi, Yes I know this, but does this pin also include the termination components on the schematic?

What termination componentsvdo you mean?
The pin is exactly the same as the ufl connector
