Note: Matrix modules should be mounted so the antenna is overhanging the board edge. This will provide the best antenna performance
for the PCB trace antenna. It is also recommended to have a ground plane on the host board underneath the rest of the module,
up to the recommended PCB edge. This will improve the antenna performance by increasing the overall ground plane.
Traces can be run underneath the Matrix module on the host PCB as long a there is an uninterrupted ground plane on one layer as
well. CEL can arrange guidance and help with the host PCB layout.
