Patent ID: 10713450

Abstract:
An ambient backscatter (transmit) communication device includes (a) an antenna arrangement for scattering electromagnetic radiation towards a receive communication device; (b) an electronic circuit having a modulator unit for modulating an impedance of the antenna arrangement in accordance with pieces of information to be communicated; and (c) a component carrier. At least a part of the antenna arrangement and/or the electronic circuit is embedded within the component carrier. An ambient backscatter (receive) communication device includes (a) an antenna arrangement for receiving ambient backscattered radiation; (b) an electronic circuit having a demodulator unit for demodulating the received ambient backscattered radiation to retrieve pieces of information; and (c) a component carrier. At least a part of the antenna arrangement and/or the electronic circuit is embedded within the component carrier. Furthermore are described a communication system and a method for transferring pieces of information by ambient backscattering.
