- In this paper, we demonstrate an RFID tag antenna manufactured by advanced inkjet printing technology on paper substrate using novel hole-matching technique for reducing the consumption of substrate material and conductive ink while attaining green RFID tags. In-depth electromagnetic analysis is performed methodologically for optimizing the parameters that effectuate the antenna dimensions. The antenna design is optimized for consistent wideband performance and extended read range throughout the complete UHF RFID band (860-960MHz), while exhibiting benchmarking results when n across cardboard cartons filled with metal or water containing objects.

- We demonstrate for the first time an RFID tag antenna which itself is humidity sensor and also provides calibration functionality. The antenna is comprised of T-matching network and horizontally meandered lines for impedance matching and reliable near-field communication. The novel contour design provides humidity sensing, and calibration functions whilst concurrently acts as a radiating element along with quadrangular capacitive tip-loading with covered middle portion for far-field communication. The inkjet printed prototypes of the antenna provide effective ambient humidity sensing while demonstrating stable RFID communication. The antenna has a compact size of 1.1 x 10.2 cm for 902-928MHz band.

- Frequency signature chipless RFID tag based on spurline resonator is presented in this letter. Resonant response of spurline is explained by analyzing the surface current distribution. Chipless tag consists of a data encoding circuit and two cross polarised monopole antennas. The tag has a data capacity of 16 bits in the range 2.13 to 4.1 GHz. Data capacity of data encoding circuit is enhanced by repositioning the spurlines. The prototype of the tag is fabricated on FR4 substrate. Developed tag can be used for cost effective identification of items in the industry.

On the efficient computation of single-bit input word length pipelined FFTs

- This letter describes an efficient architecture for the computation of fast Fourier transform (FFT) algorithms with single-bit input. The proposed architecture is aimed for the first stages of pipelined FFT architectures, processing one sample per clock cycle, hence making it suiable for real-time FFT computation. Since natural input order pipeline FFTs use large memories in the early stages, it is important to keep the word length shorter in the beginning of the pipeline. By replacing the initial butterflies and rotators of an architecture with that of the proposed block, the memory requirements can be significantly reduced. Comparisons with the commonly used single delay feedback (SDF) architecture show that more than 50% of the required memory can be saved in some cases.

Cooperative communication based barrier synchronization in on-chip mesh architectures

- We propose cooperative communication as a means to enable efficient and scalable barrier synchronization on mesh-based many-core architectures. Our approach is different from but orthogonal to conventional algorithm-based optimizations. It relies on collaborating routers to provide efficient gather and multicast communication. In conjunction with a master-slave algorithm, it exploits the mesh regularity to achieve efficiency. The gather and multicast functions have been implemented in our router. Synthesis results suggest marginal area overhead. With synthetic and benchmark experiments, we show that our approach significantly reduces synchronization completion time and increases speedup.

- On many-core Network-on-Chips (NoCs), communication is on the critical path of system performance and contended synchronization requests may cause large performance penalty. Different from conventional algorithm-based approaches, the paper addresses the barrier synchronization problem from the angle of optimizing its communication performance and proposes cooperative communication as a means to achieve efficient and scalable all-to-all barrier synchronization on mesh-based many-core NoCs. With the cooperative communication, routers collaborate with one another to accomplish a fast barrier synchronization task. The cooperative communication is implemented in our router at low cost. Through comparative experiments, our approach evidently exhibits high efficiency and good scalability.

Tidskriftsartikel (refereegranskat)abstract
- In this letter, 8-bit paper based printable chipless tag is presented. The tag not only justifies the green electronic concept but also it is examined for sensing functionality. The compact tag structure comprises of seven L-shaped and one I-shaped dipole structure. These conducting tracks/dipole structures are of silver nano-particle based ink having a conductivity of 1.1 × 107 S/m. Each conducting track yields one bit corresponding to one peak. The tag design is optimized and analyzed for three different flexible substrates i.e. paper, Kapton® HN, and PET. The tag has ability to identify 28 = 256 objects, by using different binary combinations. The variation in length of particular conducting strip results in a shift of peak for that specific conducting track. This shift corresponds to logic state-1. The response of the tag for paper, Kapton® HN, and PET substrates is observed in the frequency band of 2.2-6.1 GHz, 2.4-6.3 GHz, and 2.5-6.5 GHz, respectively. The tag has an attractive nature because of its easy printability and usage of low-cost, flexible substrates. The tag can be deployed in various low-cost sensing applications.

- In this paper chipless RFID tag, capable of carrying 9-bit data is presented. The tag is optimized for several flexible substrates. With growing information and communication technology, sensor integration with data transmission has gained significant attention. Therefore, the tag with the same dimension is then optimized using paper substrate. For different values of permittivity, the relative humidity is observed. Hence, besides carrying information bits, the tag is capable of monitoring and sensing the humidity. The overall dimension of the tag comprising of 9 ring slot resonators is 7 mm. Due to its optimization on the paper substrate, the tag can be an ideal choice for deploying in various low-cost sensing applications.

- This paper proposes self-selection pseudo- circuit (SP), a simple and effective approach to increase switch connection reusing rate and improve the network performance. It especially suits the network in which the performance is dominated by the number of hops. In SP scheme, multiple switch connections are allowed to be reserved for one inport, and the flit can reuse the partial switch connection(s) based on the routing information. For the evaluation with the traces from Splash-2, SP reduces the interconnection latency by up to 21.6% (16.9% average) with 16-core CMP configuration, and 22.2% ( 19.5 on average) with 64- core CMP configuration. Evaluated with synthetic traffic, the proposed scheme decreases the latency up to 19% ( 16% average).

FSS inspired polarization insensitive chipless RFID tag

Ingår i: IEICE Electronics Express. - : Institute of Electronics Information Communication Engineers. - 1349-2543. ; 14:10

Tidskriftsartikel (refereegranskat)abstract
- A polarization insensitive, compact, fully-passive bit encoding structure exhibiting 1 : 1 resonator-to-bit correspondence is presented. Inspired by frequency selective surface (FSS) based microwave absorbers, the structure readily operates as a chipless radio frequency identification (RFID) tag. The unit cell is composed of several concentric hexagonal loops. Finite repetitions of the unit cell constitute the proposed RFID tag in its entirety. The required bit sequence is encoded in the frequency domain by addition or omission of corresponding nested resonant elements. A functional prototype is fabricated on a commercial-grade grounded FR4 substrate, occupying a physical footprint of 23 × 10mm2 while offering a capacity of 14 bits. The proposed tag boasts a minuscule profile, and demonstrates polarization insensitivity as well as stable oblique angular performance.
