This paper represents several designs of microstrip 3D antenna arrays suitable for fifth generation mobile communication systems as well as mm-Wave imaging systems for cancer detection. Antennas presented show improved characteristics in terms of compact size and multi-directional radiation patterns associated with high gain values. This study implements array designs and fractal geometry for the purpose of miniaturizing the antennas. Triangle-fractal-shape microstrip antenna is designed and fab...
Wireless Sensor Networks (WSN) has proliferated in the past decade. These networks consist of massive number of battery-powered nodes distrusted over a given area. The nodes are responsible for sensing the environment and delivering the sensed data to a central point, named sink node. In order to reduce the power consumption of these nodes, sleeping/waking scheduling strategy has been proposed. In this work, a new hybrid sleeping/waking scheduling algorithm is proposed based on graph theory metr...

Missing data is a common problem confronted by researchers in machine learning applications. Missing values affect both the performance of analysis tools, as well as the quality of the drawn decisions. This research aims to analyze the impact of four missing data treatment methods on the predictive accuracy of the C4.5 decision tree algorithm. It also investigates the imputation accuracy of each imputation method using a single dataset with missing values presented in a single variable. The work...

A new ultra-compact multiband Bio-inspired antenna using a Vitis vinifera half-leaf-shaped with embedded arc-slits as the radiating patch is presented in this paper. The miniaturization is realized using the asymmetric feeding technique. Duroid 5880 with a dielectric constant of 2.2 and a thickness of 1.57 mm is used as the substrate of the proposed structure. The antenna dimension is 0.21λd×0.11λd at 1.95 GHz. The design is made up of five arc-slitted Vitis vinifera semi-leaf-shaped radiating p...
In this paper, an innovative compact pattern reconfigurable antenna is proposed and developed to establish an inter-satellite communication link between the Formation flying spacecraft. The reconfigurable beam switching antenna comprises a driven Monopole at the center, encompassed with four Reconfigurable Selective Reflectors (RSR) which act as RF radiators and reflectors for different switching conditions. PIN diodes are used to electronically control the switch states of RSR and beam switchin...

A novel planar antenna for dual-linear-polarized applications, based on Substrate Integrated Waveguide (SIW) technology, and its dual-mode transceiver, acting as Orthomode Transceiver (OMT), are presented. TE10 and TE20 propagation modes are excited on the SIW to feed two orthogonal slots at the same time, operating at the same frequency band. Each slot produces the radiation according to the current distribution corresponding to their own mode without mutual interference. A dual-mode feeder and...

This paper develops and comprehensively evaluates a very simple and remarkably efficient method, here referred to as the Quasi-Moment-Method (QMM), as a tool for the calibration of basic (classical) pathloss models, in various radiowave propagation scenarios. After a succinct description of the characterizing features of the method, the paper presents computational results involving comparisons with published data concerning Minimum Mean Square Error (MMSE) optimization, Adaptive Neuro-Fuzzy Inf...
