Big RF solder pad can result in great parasitic capacitance, which will affect the antenna performance.
Remove the copper on the first and second layers under the RF solder pad.

To adopt RF antenna connections, the GSC RF connector MM9329-2700RA1 from Murata is
recommended. Figure 3-3 shows the encapsulation specifications.
