RociPi Wireless A3 Module Antenna Matching

We have bought the ROCK Pi Wireless Module A3 to use in RockPi N10.
According to the schematic in below link, we wonder the 50 Ohm RF trace is matching or not.

We also make some simple diagram for your reference

The question is whether the A3 module has appropriate RF matching or not?

Because we assume this module is ready for production, no further matching adjustments are required.

If you use the antenna comes with the module, it’s already tuned.

Hi Jack
Thanks for your reply.
Could you provide the smith chart for matching status?
