If the antenna SR42W001 is placed on layer 1 near the edge of the PCB, and layer 1 is also populated with a lot of components so there isn't much of a GND plane on layer 1 but there is a solid GND plane on layer 2, how many stitching vias are required to connect pin #2 (GND) of the antenna to layer 2 ? Does the antenna need to have GND vias all along the perimeter of the antenna, or just one via near pin #2, or other ?
