Small series of me, I will say that the antenna coil, why? It has the function of induction, in the whole circuit it is the leading role, as the induction to connect to other electronic components. Antenna coils may give us a false impression that the antenna coil is only on the antenna. In fact, it is not surprising that this idea, antenna coil is so special. Then we expect the antenna coil to give us more surprises.
