US 2018/0323828 A1 · SINGLE ANTENNA-BASED WIRELESS CHARGING AND NEAR-FIELD COMMUNICATION CONTROL APPARATUS AND USER TERMINAL THEREFOR

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.

An apparatus for controlling wireless charging and short-range communication on the basis of a single antenna, the apparatus comprising:

a switch controller configured to detect a resonance frequency from a rectifier input signal of a power receiving unit, determine whether the detected resonance frequency is a first frequency for performing wireless charging using a single antenna or a second frequency for performing short-range communication using the single antenna, and generate a control signal;
and
a switch configured to be turned on or off according to the control signal received from the switch controller in order to perform wireless charging or short-range communication.

A user terminal comprising:

a resonator including a single antenna for wireless power signal reception and short-range communication;
a power receiving unit configured to receive a wireless power signal using a first frequency signal that is resonated by the resonator;
a short-range communication module configured to perform wireless communication using a second frequency signal that is resonated by the resonator;
a switch controller configured to detect a resonance frequency from a rectifier input signal of the power receiving unit, determine whether the detected resonance frequency is a first frequency or a second frequency, and generate a control signal;
and
a switch configured to be turned on or off according to the control signal received from the switch controller to perform wireless charging or short-range communication.
