Antenna Information
The EMC328x has two specifications, PCB antenna and external antenna. Please refer to the order code
for ordering. The IPX antenna connector is not soldered to the module using the PCB antenna. Better RF
performance can be achieved by connecting an external antenna through an IPX connector.

8.1.2. PCB Antenna use points
When using the PCB antenna on the module, you need to ensure that the distance between the
motherboard PCB and other metal devices, connectors, PCB vias, traces, and copper is at least 16mm.
The shaded areas in the figure below need to be kept away from metal components, sensors, sources of
interference, and other materials that may cause signal interference.
