Abstract
In this paper, a novel matching network, which is used in the contactless financial IC card, is provided. This matching network can obtain higher energy transmit efficiency than the customary matching method. The functional simulation and hardware simulation showed that the current-carrying capacity can be increased from 5mA to 9mA, nearly 80% improved, and the Q-factor is also better. It is very meaningful in the application of the high power consumption application like the contactless financial IC card.
