AWR6843: I want to know about the ground area of the AWR6843ISK antenna.

Part Number: AWR6843

Hi~

1. Why did you SILVER PLATING the GND area around the antenna after opening the PSR as shown in the picture below?

2. Why surround the GND around the antenna as shown in green in the picture below?
   - If it's because of noise, is it good to design the GND as wide as possible?
