CC3220SF: queries regarding CC3220SF PCB antenna

Part Number: CC3220SF

Hi,

There are a few queries regarding CC3220SF. We are planning to use the SoC in our upcoming product.

I am not able to find sufficient stock for this chip. Will it be out of production soon?

Is there a reference design available for the PCB antenna? I can see there is a Module available with a PCB antenna but no design document I can find which provides details about the antenna and its performance.

The chip antenna provided in the launchpad is not meeting our specifications. Is it possible to use the below antenna?
