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.

Claim (Index 20):
The method as set forth in  claim 18 ,\n wherein modulating the impedance of the antenna arrangement of the transmit communication device comprises modulating a strength of absorption of at least a part of the emitted electromagnetic radiation with the time varying pattern; and/or modulating the impedance of the antenna arrangement of the transmit communication device comprises modulating a frequency of absorption of at least a part of the emitted electromagnetic radiation with the time varying pattern; and/or wherein, at the transmit communication device, impedance values of the time varying pattern of the impedance are chosen such that a modulation depth of the entire radiation received by the receive communication device is maximized; and/or wherein the method further comprises, at the receive communication device, filtering the received scattered and modulated electromagnetic radiation, wherein the demodulator unit demodulates the filtered received scattered and modulated electromagnetic radiation.
