This paper presents a new reconfigurable carrier leakage canceler for UHF RFID readers, using a directional coupler and an impedance tuning circuit to improve the sensitivity of the receiver. The impedance tuning circuit, which consists of electrically tunable passive components, can be adaptively tuned to have an optimum reflection coefficient for carrier leakage cancellation. In order to secure...
Wireless personal area networks (WPAN) systems for the communication in the indoor environment have been developed according to the growth of the ubiquitous technology. IEEE 802.15.4a is a standard which describes the indoor communication systems for the ultra-low complexity and power consumption. Implementation of PHY for IEEE 802.15.4a employs ultra-wide band (UWB) technologies which have the advantage...
