Document Type and Number:
WIPO Patent Application WO/2019/208843
Kind Code:
A1
Abstract:
The present invention relates to an apparatus and a method for performing transmission and reception of wireless power. The apparatus comprises: a transmission signal processing unit configured to generate a transmission data signal and perform a modulation and an amplification; a transmission antenna configured to convert the transmission data signal into an RF signal and transmit the RF signal; at least one reception antenna configured to receive at least one of the RF signal or an external signal received from the outside; a wireless power reception unit configured to harvest power from the RF signal received through the at least one reception antenna; and a reception signal processing unit configured to demodulate the external signal received through the at least one reception antenna. Since the RF signal, which is radiated by the apparatus itself, is received again and utilized for power charging, energy can be recycled.
