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?
Hi,
1. This is GND with rogers material separate from the L2 ground for the ball to gcpw transition.
2. Yes and Yes.
