    Question about the L-shaped Ground in PCB Layout of BCM20737S

      Hi all,

      I have a question about the PCB layout of BCM20737S, since it uses an embedded antenna, we have to make sure our layout won't affect its RF performance.

       

      I have read the layout suggestions in BCM20737S datasheet and the reference design.

       

      Questions:

      There is a L-shaped ground around the BCM20737S chip, in datasheet it says this L-shaped ground is required for the embedded BLE antenna, and we need to keep GND continuous. My question is: should we connect this L-shaped ground to the GND pins of BCM20737S chip? Or should we just place the L-shaped ground close to the chip but not connect to any pin?

       

      Thanks
