2.6.1 PCB Antenna

For the RNWF11PC Module, the PCB antenna is fabricated on the top copper layer and covered in solder mask. The layers below the antenna do not have copper trace. The recommendation is to mount the module on the edge of the host board, and ensure there is no PCB material beneath the antenna structure of the module, as well as avoid any copper traces or planes in that specific area of the host board. Also, verify the maintenance of antenna tuning when integrating the module onto a host board or end-product.
