RECONFIGURABLE ANTENNA APPARATUS FOR WIRELESS POWER TRANSFER OF LOW FREQUENCY AND NEAR-FIELD COMMUNICATION

摘要

Frequency matching is performed by using one receiving antenna and controlling the switching capacitance and inductance between an RF front-end of a wireless power transmission and an NFC system, and an antenna. An antenna apparatus for wireless power transmission and near-field communication according to the present invention comprises: a chip including a wireless power reception front-end, an NFC front-end, an NFC and wireless power reception integrated system to drive the wireless power reception front-end and the NFC front-end, a switching capacitor array, an inductor array controller, a matching circuit and an LC switching control module; and a receiving antenna module in which one receiving antenna and an inductor array are formed.
