In this paper, the design and simulation of a Radio Frequency Identification (RFID) antenna is presented. The antenna is designed in order to maintain a small size while operating on metallic surfaces. This RFID antenna with an appropriate chip is intended to be used as RFID sensor. The RFID tags designed for metallic environment have to overcome certain drawbacks regarding the effects of metal to the performance of the antenna. These effects are being addressed in this work and certain solutions are explored. Finally the results of the simulation of the antenna are presented to evaluate the performance of the antenna.

The Ultra High Frequencies (UHF) Radio Frequency Identification (RFID) chips generate harmonic signals due to their nonlinear circuits. Usually these harmonic signals are seen as harmful because they are considered as efficiency losses or potential sources of disturbing signals. This paper overviews several recent works demonstrating that the harmonic signals produced by the UHF RFID chips could be source of new capabilities for the tags.

In this paper, a development of aperture coupled based microstrip antenna using meander line slot is presented. The proposed antenna constitutes of 2 substrate layers which are separated by a common ground plane. A Meander line slot is loaded to the antenna patch to reduce the dimension of the proposed antenna design. The antenna characteristics before and after applying a meander line slot are numerically investigated. Compared to the reference antenna design, using a meander line slot loaded to the antenna patch, it can achieves several performance improvements. These improvements are not only in terms of size reduction, but also in terms of bandwidth enhancement and antenna efficiency.

HF communications can be difficult in the polar regions since they are strongly influenced by space weather events. Airline communications within the polar regions rely on HF communications and improved nowcasting and forecasting techniques in support of this are now required. Previous work has demonstrated that ray tracing through a realistic, historical ionosphere provides signal coverage in good agreement with measurements. This paper presents an approach to providing a real-time ionospheric model by assimilating TEC measurements and validates it against observations from ionosondes.

This summary presents a proof of concept for a passive chipless wireless sensor for temperature range detection. The temperature range information is encoded in a binary format using dual C-like scatterers operating at two different frequencies. The sensing principle is based on resonance shift of the Radar Cross Section (RCS) peaks of the backscattered signal from the two adjacent scatterers. This shifts the reflected power maximum in or out of the bands mapping it to logic ‘1’ or logic ‘0’. The European and ISM bands are chosen for wireless sensor compliance with commercial RFID readers communication standards. This is an attempt to use the conventional RFID standards reader for chipless sensing.

Monitoring of partial discharge (PD) activity within high voltage electrical environments is frequently used for the assessment of insulation condition. Traditional measurement techniques employ technologies that require either offline installation or high power consumption and cost. A wireless sensor network is proposed that utilizes only received signal strength to locate partial discharge within a high-voltage electricity substation. The network comprises low-power and low-cost radiometric sensor nodes which receive the radiation propagated from a source of partial discharge. Results are reported from a test performed within a large indoor environment with a network of nine sensor nodes. An emulated PD source was placed at multiple locations within the network. Signal strength measured by the nodes is reported via WirelessHART to a data collection hub where it is processed using a location algorithm. The results obtained place the measured location within 2 m of the actual source location.

Microwave imaging is a promising imaging modality for the early detection of breast cancer. The two most important signal processing components of a radar-based microwave imaging system are the early-time artifact removal and the image reconstruction algorithm. Several image reconstruction algorithms have been developed and their performance has been evaluated in a number of studies. However, most of these evaluation studies were either performed on numerical breast phantoms or used an idealized artifact removal algorithm. In this paper, a range of both data independent and data adaptive imaging algorithms are evaluated using experimental breast phantoms in combination with a realistic artifact removal algorithm. The clutter rejection capabilities of each algorithm are assessed in the presence of experimental noise and residual artifacts using a range of appropriate image quality metrics.

The ‘TALON’ architecture has been proposed to meet the unprecedented processing requirements and flexibility required for the Square Kilometre Array-Phase-1 (SKA1) Mid telescope, Correlator & Beamformer (Mid. CBF). The high-performance hardware platform of the TALON architecture incorporates two variants of TALON line-replaceable-units (LRUs); TALON-SX and TALON-MX. Each LRU features a single Intel Stratix-10 FPGA, 2 DDR4 DIMM modules, 4 100GE QSFP28 ports and 48 26 Gbps bi-directional optical channels that connect to a custom optical-backplane. Each LRU facilitates up to 7 TMAC/s of processing capability, 512 GB/s of memory bandwidth and 1.648 Tb/s of I/O capacity.

Future smart grid services are likely to be deployed in a distributed fashion in order to achieve a reasonable system management complexity. An adequate communication infrastructure is then crucial to enable scalable and seamless operations in the electrical grid. The paper main contribution consists of a quantitative evaluation of the quality of service in different wired and wireless communication systems, applied to two use case scenarios: the “collaborative load shedding for frequency support” and the “distributed optimal power flow management in a dc grid”.

Synthetic Aperture Radar (SAR) is one of the favorite sources for sea near-surface wind speed retrieval. For this problem, wind speed is principally estimated based on the empirical (EP) models, namely CMOD functions, which are constructed by the observations from spaceborne microwave scatterometers (ERS-1/2). Little studies have mentioned the use of electromagnetic (EM) models for wind speed estimation, probably due to their complicated descriptions. However, it is reasonable to compare wind speed estimates based on the two approaches, since both of them describe the relation of radar scattering and wind field, directly for EP models and via wave surface roughness for EM models. Based on the comparisons, some ideas are proposed to improve the performance of EP and EM models.
