When using the Telit LE920, since there’s no antenna connector on the module, the antenna
must be connected to the LE920 antenna pad (AU9) by means of a transmission line
implemented on the PCB.
In the case that the antenna is not directly connected at the antenna pad of the LE920, then a
PCB line is required in order to connect with it or with its connector.
