Abstract
Disclosed are a single antenna-based wireless charging and near field communication control apparatus and a user terminal therefor. A single antenna-based wireless charging and near field communication control apparatus according to one embodiment comprises: a switch control unit for detecting a resonance frequency from an input signal of a rectifier in a power receiver and determining whether the detected resonance frequency is a first frequency for wireless charging using a single antenna or a second frequency for near field communication using a single antenna, to generate a control signal; and a switch which is turned on/off for wireless charging or near field communication according to the received control signal from the switch control unit.
