Multipurpose Antenna Array for Backscattering, Reconfigurable Intelligent Surfaces and MIMO Communications

Résumé

Energy consumption of mobile network is a major issue. One solution is to use antenna arrays to focus RF field on the receiver. But recently two other techniques have been also proposed. First the RIS are programmable mirrors which can be used to redirect a RF wavefront emitted by a source toward one or several receivers. Second the ultra-low power backscattering devices recycle the ambient RF field to transmit information. Actually, the best energy aving approach depends on many different parameters. So here we propose a multipurpose antenna array (MAA) able to manage these three operating modes simultaneously. The MAA switches between the different modes thanks to an electronic circuit made of PIN diodes. We propose a simple model of MAA based on impedance analysis. Finally, we evaluate experimentally the performances of the three operating modes of a MMA made of 4 patch antennas working at 3.7 GHz.
