When using the LE910, since there's no antenna connector on the module, the antenna must
be connected to the LE910 antenna pad (K1) by means of a transmission line implemented on
the PCB.
In the case the antenna is not directly connected at the antenna pad of the LE910, then a PCB
line is needed in order to connect with it or with its connector.
