PCB layout and antenna pin numbering

The antenna uses PIFA technology and should thus be mounted on a ground plane. If there are several layers in the

PCB, there is an advantage to add vias for smooth interconnection of the ground areas to avoid splits in the ground

plane. It is also important that there is a ground clearance around the NC pads and the RF feed pad, through all layers

of the PCB. It is recommended to implement a matching network to optimize the antenna impedance in your

application. The components can be positioned under the antenna. See recommendations in the figures below.
