Dual-Polarized Through-Wall Repeater for the Wireless Reading of Millimeter-Wave Passive Sensors

Abstract : This paper reports the reading of passive and chipless millimeter-wave sensors using a dual-polarized through-wall repeater. The reader is here a millimeter-wave frequency-modulated continuous-wave (FMCW) Radar, and the batteryless sensor corresponds to a chipless sensing device whose cross-polarized electromagnetic reflectivity depends on the applied pressure. The proposed dual-polarized repeater allows transmitting two different and orthogonal electric field polarizations. The feasibility of through-wall reading of sensors is demonstrated here at 24 GHz from a passive pressure sensing device.
