This article presents compact wideband four elements Many-Input Many-Output (MIMO) antenna using Defect Ground Structure (DGS). The proposed structure is dedicated to cover 4G-LTE/Sub 6 GHz bands in the 2.5/3.5/5.5 GHz frequency range and WLAN, Wi-Fi, and (LTE bands 41, 42, 43, 46, and 48). It also includes new radio (NR) technology which has different bands for 5G and (sub-6 GHz bands 47, 48). The designed antenna is very compact in size having dimensions of 28 mm x 29.58 mm x 0.8 mm. Isolation is achieved with square ring resonators (SRR). Isolation is further enhanced by inserting slots and SRRs between antennas. MIMO antenna characteristics such as high isolation (45 dB), low envelope correlation coefficient (0.01), and high diversity gain (10 dB) are measured. Furthermore, a wide impedance bandwidth of 8 GHz is measured. MIMO antenna is verified with a Software-Defined Radio (SDR) platform.

In this paper, we offer a blockchain-based approach for efficient product tracing in the pharmaceutical supply chain that uses smart contracts and decentralized storage. The smart contract ensures data provenance, eliminates the need for mediators, and provides all participants with a safe, immutable transaction history. We provide the smart contract system architecture as well as the detailed algorithms that regulate our proposed solution’s operating principles. We test and validate it to see how effective it is at improving traceability in pharmaceutical supply chains.

The delivery of medicine directly from the manufacturer to the end-user is the highest priority of today's healthcare system. Several stakeholders, including distributors, suppliers, wholesalers, and consumers, are involved in the pharmaceutical supply chain. However, verifying the source of raw materials and maintaining visibility of goods and merchandise as they move across the supply chain network has become increasingly difficult thus, forming opportunities for counterfeits to enter the authentic supply chain. This paper proposes using the Internet of Things (IoT) and Blockchain to improve traceability in the pharmaceutical supply chain. Blockchain-based on the IoT is a type of distributed ledger (DLT) that keeps an immutable record of all transaction data that cannot be falsified and is transparent to all stakeholders. Implementing an IoT-based blockchain system will give pharmaceutical industry the resources it needs to enhance drug traceability across the supply chain, resulting in more effective and safe healthcare.

In this paper, some theoretical aspects and experimental results are discussed with the aim to provide supplementary dc energy to radio frequency identification (RFID) tags by exploiting the nonlinear nature of rectifier devices. Three nonlinear phenomena are treated: (i) the impedance power dependence, (ii) the harmonic production, and (iii) the dependence on the radio frequency waveform. The novelty of the work relies on proposing a double rectifier composite system in where the nonlinearity of each rectifier is exploited to enhance the global powering performance of the system. Using the passive RFID technology as a beacon for the implementation, the approach considers combining the internal rectifier circuit of a commercial RFID chip operating at 868 MHz with an external rectifier circuit operating at 2.17 GHz. The solution triggers in a composite system RFID tag-harvester integrated in a single-feed dual-band antenna. The experimental validation shows 5 dB of tag sensitivity enhancement when it is empowered by the external harvester. The enhanced sensitivity produces an increase in the theoretical reading range distance from 3.3 to 6.1 m.

This paper presents the RF power harvesting system. The design goes through three major phases. In the first phase, dual band antenna is designed that operates in GSM900 and WiFi 2.45 GHz bands. This is a dual band dual feed antenna that provides excellent frequency response and fairly omni directional radiation pattern. In the second phase, rectenna design is carried out to convert received RF power into DC voltage. Impedance matching and power combining included in the circuit here ensures maximum power transfer to the passive RFID chip and the rectifying circuitry. Nonlinear effects of the rectifier element are also studied and included in the co-simulation. Third phase consists of co-simulation to mitigate any integration issues of first and second phase. The final integrated system provides RF-to-DC conversion efficiency around 30% at 2.45 GHz. A sufficient isolation is provided at both frequencies to support an RFID communication and at the same time, harvesting from the 2.45 GHz band.

A new approach of integrating the passive UHF Radio Frequency Identification (RFID) technology with electromagnetic energy harvesting function is presented in this letter. The approach is based on using a passive RFID tag operating at 868 MHz for communication purposes whereas a rectifying circuit is designed to harvest its third harmonic i.e., 2.604 GHz generated by the non-linear behavior of the RFID chip. An innovative concept to re-inject the energy harvested into the RFID chip is proposed. Experimental results on the energy feedback operation has shown an RF-to-direct current (dc) conversion efficiency of 33% at -16 dBm input power for the harvesting function and a read range improvement of 2.5 m for the communication function.

This paper proposes the use of a passive RFID light sensor in a daylight-adaptive lighting system. In such a system, the dimming levels of light sources are adapted to changing daylight such that a desired illuminance distribution is achieved at the place. The system is composed by photo-sensible passive RFID tags used as light sensor nodes and RFID readers connected to a central controller. The use of the passive UHF RFID technology avoids the use of complex feedback light control algorithms as also simplify the deployment of the sensor network. Experimental results showed the proposed solution. The light variations can be sensed with high resolution having completely passive and wireless sensors.

In this paper, a design approach for the efficient integration of passive RFID tag operating at UHF 868 MHz for RFID communication and a rectifier operating at 2.45 GHz for energy harvesting application, both in a single feed dual band antenna is presented. Initially, the RFID chip and the rectifier element were characterized. Therefore, the step by step design process for the integration of each element is carried over, for a maximum power transfer to the passive RFID chip and the rectifying circuitry. The non-linear effects of rectifier and RFID chip are considered in an electric-electromagnetic co-simulation, ensuring the conditions at the threshold activation power at the RFID chip. 36.9 % RF-to-DC conversion efficiency is ensured at 2.45 GHz for -10 dBm input power. The sufficient isolation is provided at both frequencies to support an RFID communication and at the same time, harvesting from the 2.45 GHz band.

Since RFID is wireless technology, it enables the identification from a distance, depending upon the read range of the tag. There is a vast requirement of RFID technology in security, military, health-care, airline, library, sports, farming and other applications, not only for identification but as a sensor to monitor different parameters related to these fields. RFID based environmental sensor can be designed with the integration of sensing material in a microstrip antenna. The properties of the sensing material are responsible for converting a passive tag as a sensor. Here, RFID based passive chemical vapor sensor is presented doped with the conducting polymer. A sensitive Polystyrene Sulfonate is used as sensing material to integrate in H-shaped slot of PIFA like tag. The designed tag working at 870 MHz is characterized by turn-on and back-scattered power measurements. The experimental results are also presented by considering known and unknown percentage of water vapor and the moisture levels.

Passive ultra high-frequency radio frequency identification tags, besides item labeling, are also able to exploit capability to sense the physical state of the tagged object as well as of the surrounding environment. Here, a new family of polymer-doped tags are proposed and fully characterized for the detection of ambient humidity. A sensitive chemical species based on PEDOT:PSS is used to load a shaped slot, carved into a folded-like patch tag. The communication and sensing capabilities of the resulting radio-sensor are investigated by means of simulation and measurements that show how to control and balance above opposite requirements by a proper deposition of the sensitive material. The device could have interesting applications in the assessment of the air quality within living and controlled rooms, in the monitoring of the conservation state of foods, in the preservation of walls, and even in the medical field, e.g., to monitor the healing of wounds.
