A slotted tag antenna is presented for blood bag monitoring with good reading distance. In addition to the main radiating patch, cuts made into the ground to increase the antenna radiation efficiency and help to self-match the antenna impedance with the RFID microchip NXP G2XM IC chip in TSSOP8 (SOT505-1). The antenna structure is uniplanar and optimized to be mounted on a high-permittivity (Blood Bags) and to work in the UHF European band (865–868) MHz. Furthermore, an equivalent circuit model is presented and the characteristic of the proposed RFID tag antenna predicted by this circuit model are in good agreement with the full wave simulations. The obtained simulated show a read range of 1.28 meters when mounted directly on the Blood Bag.

We will present an RSA algorithm designed for remote visualization of medical images with data security transfer. This interface is implemented under MATLAB environment. The implementation of the image cryptography system uses the RSA algorithm with 64 bits private key length. The transfer of images in a secure way for medical diagnosis is insured by generating a watermarked key to encrypt the original image. More, we introduced a comparison study between the obtained performances and those computed with other algorithms such as AES, DES and IDEA.

In this work, a novel frequency-reconfigurable printed antenna is proposed. The structure consists of a capacitively loaded loop (CLL) introduced into the near field region of a printed monopole antenna to create multifrequency behavior. The frequency agility was realized by integrating a lumped capacitor between the CLL and the ground plane. A tuning range of 0.654-0.886GHz is successfully achieved when varying capacitance values from 0.5 to 4pF covering LTE and GSM bands while keeping the operating frequency F1=2.65GHz of the reference antenna changeless. The simulated results of return loss, surface current distribution and radiation patterns are presented and discussed.

in this paper a new method for the analysis of non uniform substrate integrated waveguide transmission lines is developed. The proposed approach uses the method of moments with frequency dependent basis functions derived from the structure's propagation characteristics. The stability and speed of this method are demonstrated by analyzing non uniform structures. The obtained results for a structure with periodically varying width were compared to those obtained by HFSS simulations and a good agreement has been observed with much lower computation time.

This paper presents a design of a CMOS digitally controlled oscillator (DCO) using a tunable active inductor (TAI) to reduce the area and cost for reconfigurable multi-band RF applications. The compatibility of this circuit to different wireless standards shows its potential to be implemented for the Internet of Things (IoT). The proposed TAI, based on a gyrator-C topology, achieves coarse frequency tuning due to a 4-bit digitally controlled current source. Implemented in 130 nm CMOS technology, the DCO occupies an area of only $(52 times 48) mumathrm{m}^{2}$. The circuit offers a frequency tuning from 1.65 GHz to 2.5 GHz for a 4-bit digital control word in [1], [15]. The optimal phase noise is about −87 dBc/Hz@1 MHz offset with power consumption varying from 2.6 mW to 5 mW at a supply voltage of 1.1 V when changing the control word digitally from 1 to 15.

In this paper, we propose a novel method based on latent low-rank representation theory (LatLRD) for pansharpening, which aims to synthesize a high resolution multispectral (MS) image from a high resolution panchromatic (PAN) image and a low resolution MS image. Exploiting the property of the low-rank of the MS data, the LatLRD is first performed on the up-sampled MS image and the PAN image to reconstruct a composite image in order to preserve the spectral fidelity of MS images, while transferring spatial structures. Second, a multi-scale procedure is applied to the generated composite image from the LatLRD decomposition for extracting the spatial information. Finally, the details are injected to the up-sampled MS bands to obtain the corresponding MS image at fine resolution. Experimental results demonstrate that the proposed approach performs better than several state-of-the-art methods in enhancing the spatial quality and preserving the spectral fidelity.

A Wireless sensor network is a collection of sensor nodes which are limited energy resources. Therefore, the main issue is how to optimize the energy consumption to maintain the sensor nodes alive as long as possible. In this paper, we propose a new algorithm that divides the network area to zones and uses the fuzzy logic method to select Cluster Heads (CHs). To this aim, we have taken into account a set of parameters related to the node for selecting CHs. These parameters are used as inputs to the Fuzzy Inference System. Simu-lation results show that our algorithm succeeds to increase the stability period, save the energy and hence, prolong the lifetime of the network.

Due to the rapid growth in the use of wireless communication systems, there has been a recent increase in public concern regarding the exposure of humans to Radio Frequency (RF) electromagnetic radiation. This is particularly evident in the case of mobile telephone handsets. Previously, the insertion of a ferrite sheet between the antenna and the human head, the use of conductive materials (such as aluminum), the use of metamaterials (SRR), frequency selective surface (FSS), and electromagnetic bandgap (EBG) structures to design high performance devices were proposed as methods of reducing the SAR value. This paper aims to provide an investigation of the effectiveness of various available Specific Absorption Rate (SAR) reduction solutions.
