    Abstract:
    In this paper, we present an active ultra-wideband (UWB) reflector for radio frequency identification (RFID) and wireless sensor applications. The tag is composed of a receiver UWB antenna connected to a broadband amplifier. Its output is connected to a cross-polarized transmit antenna. In order to increase the battery lifetime, an UHF link is used to wake up the microcontroller. It modulates the radar cross section of the tag by turning the amplifier bias on and off. The amplitude of the reflected UWB pulse sent by the UWB reader is modulated as a result. The basic theory of operation of ultra-wideband radio identification systems is explained in this paper. A proof of concept using commercial components and experimental results obtained with an ultra-wideband radar are presented.
