CLM920_TE3, Diversity antenna need to obtain better RF performance, it is necessary to
reserve PI matching circuit. Parameters can be matched according to board of the customers,
and the 68~100nH inductor can be connected to the ground to prevent static electricity.
Attention is paid to the impedance matching and antistatic or lightning stroke of the antenna.
