In contrast to pure identification labels, passive inductive coupled RFID transponders with enhanced functionality have an increased power consumption. A nonoptimized antenna design for high power transponders may lead to a poor efficiency and high magnetic field emissions. Therefore, in this work, the energy transmission of inductive coupled systems is(More)
Skyrocketing growth in the cellular personal communications services (PCS) sector has fueled the needs for higher density, more functionality, and greater performance on both handset and basestations. Third generation wireless standards, which require hardware upgrades, loom on the horizon. RF component suppliers are scrambling to find solutions at the IC,(More)
For indoor localization systems Radio Frequency Identification (RFID) is an often chosen technique. This paper uses Received Signal Strength Indicator (RSSI) values from passive UHF RFID labels for the localization process. Based on the measurements of these RSSI values a formula is derived to describe the relation between distance from tag to antenna as(More)
Due to the increased use of Radio Frequency Identification (RFID) in different fields of application it is reasonable to explore the benefit that can be obtained by the simultaneous localization of RFID tags. This paper describes the localization of a passive UHF RFID tag via Extended Kalman Filter (EKF) and Unscented Kalman Filter (UKF) using the Received(More)
To accomplish location-awareness in indoor scenarios Radio Frequency Identification (RFID) tags are often used for the localization. This paper only uses Received Signal Strength Indicator (RSSI) values from passive UHF RFID labels for the localization process. The RSSI values of reference tags (RTs) for which the locations are known are employed as side(More)
