APEX/APEX LT
The footprint recommends the APEX/APEX LT module is to 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 only improve the antenna
performance by increasing the overall ground plane.
Traces can be run underneath the module on the host PCB as long a there is an uninterrupted
ground plane on one layer as well. LS Research will provide any guidance and help with the
host PCB layout.
