“…For each receiving signal, the sampling frequency of the reader is very low compared with the UWB, and the acquisition process is shifted in time of few picoseconds. After the end of the acquisition process, the reader rearranges all the acquired samples in order to reconstruct the backscattered signal from the tag and finally identify its ID [2]. The Fig.…”

This paper presents a potentially low cost low sampling noise reader for the Ultra Wideband (UWB) Chipless Radio Frequency Identification (RFID) technology. The reader is designed around the time equivalent approach to reduce its realization cost. A significant effort has been spent for the schematic and layout optimization in order to obtain a very low sampling noise system. This latter aspect is very important to realize a suitable reader for UWB RFID Chipless technology. It is demonstrated that with an accurate design, is possible to realize a low cost equivalent time acquisition system with performances comparable with a high cost real time acquisition system. It is possible acquiring, an UWB impulse of only 70 ps width with high precision.

“…In turn the tag reflects the incoming signal shaping it. The reader can decode the ID of the tag analyzing the shape of the backscattered signal, in time for time-coded tag, or in frequency for frequency-coded tag [2]. Actually, there is not UWB Chipless RFID reader available in commerce.…”

“…The value of the read distance is clearly strongly dependent on the sensitivity of the receiver. Since the most suitable architecture of a chipless receiver is currently object of research [13] and its development is challenging due to the required wide bandwidth, sensitivity value has been set to a lower value with respect to conventional RFID readers (typically having a sensitivity of -100 dBm [14]). A receiver with a sensitivity comparable to that of conventional RFIDs would give to chipless RFID technology outmost advantages in terms of required power and/or read range with respect to conventional RFID technology.…”

High-Impedance Surfaces comprising multi-resonant elements are proposed as chipless tags. The presence of the ground plane in the structure is a key point in realizing a chipless RFID nearly insensitive with respect to the objects which the tags are placed on. The paper presents various encoding mechanisms used to design robust and compact chipless RFID tags able to work both on low-reflecting objects and on metallic structures

Abstract. This paper describes temperature measurement in the multisensor systems based on the radio-frequency identification SAW passive tags which are currently applied in the electric power systems and the switchgears. Different approaches of temperature measurement in the collision case are shown here. The study is based on the tag model with specific topology, which allows us to determine temperature through the response signal with time-frequency information. This research considers the collision case for several passive tags as the temperature sensors which are placed in the switchgear. This research proposal is to analyze the possibility of using several SAW passive sensors in the collision case. We consider the using of the different typical elements for passive surface acoustic wave tag which applies as an anticollision passive sensor. These wireless sensors based on the surface acoustic waves tags contain specifically coded structures. This topology makes possible the reliability of increasing tag identification and the temperature measurement in the collision case. As the results for this case we illustrate simultaneous measurement of at least six sensors. IntroductionModern solutions in the field of monitored parameters should meet the requirements of increased noise immunity. In addition, they should have high speed, resistance to external climatic influences, high reliability and durability in operation. Modern monitoring based on radio frequency systems should be passive (without any energy source). Such requirements are met by radio frequency identification (RFID) technology, based on the use of passive acoustoelectronic devices on surface acoustic waves (SAW) [1], [2].For temperature monitoring, RFID reader interrogates several passive SAW tags which are placed on the monitored object. However, in the simultaneous monitoring of several temperature sensors is limited to the problem of collision for passive acoustoelectronic RFID devices. In the case when several sensors are interrogated simultaneously, their response signals can overlap each other in the time domain, making it impossible to read the code of each device and obtain information about the temperature.The last analysis shows that solutions cannot satisfy the actual tasks of monitoring and control objects with a wide temperature range and certain operating conditions in the collision case. This problem is the most evident in multisensory systems which are using the electric power systems. The temperature is the most important indicator of the electrical equipment current status. It makes possible to provide information about the emergency and electrical fire caused by short circuit or overheating of the equipment in the switchgear. Monitoring systems which are applied for temperature measurement would increase reliability and safety of high-voltage equipment.
