In this paper, we present a radio-powered module with asymmetric wireless link utilizing ultra wideband radio system for RFID and wireless sensor applications. Our contribution includes using two different standards in uplink and downlink. Such as conventional RFIDs, incoming RF signal transmitted by reader is used to power the internal circuitry and receive the data. However, in upstream link, an IR-UWB transmitter is utilized. Unlike traditional RFID systems, due to great advantages of UWB communication, this tag is very robust to multi-path fading and collision problem and it is more secure against eavesdropping or jamming. The module consists of a power scavenging unit, a RF receiver, an IR-UWB transmitter, digital baseband controller, and an embedded UWB antenna are designed for integration on Liquid-Crystal Polymer (LCP) substrate, using 0.18um CMOS process technology.
