In this work, concentric ring Arrays (CRA) with non-uniform excitation are investigated, with the objective being to minimize the Sidelobe Level (SLL) for the array and keep the Directivity within an acceptable value. The optimization technique to be…

In many systems, it is essential to extract or enhance the desired information and remove the unwanted components. This is the simplest aim of signal processing where the filter turns out to be the key element. The objective of this paper is to…

Pattern synthesis of Antenna array has gained much attention over the last years as they constitute an important role in the modern communication systems. Unit circle-based techniques such as Schelkunoff null placement method have proved their…

In this work, Grey Wolf Optimization (GWO) is applied to the optimization of elliptical and concentric elliptical antenna arrays. The objective is to minimize the Sidelobe level and improve the directivity. GWO is a nature-inspired meta-heuristic…

The design of antenna arrays in a 3D geometry is presented in this Chapter. The decision variables considered for this synthesis problem are the array element amplitude excitations. The objective is to design an array which ensures minimum sidelobe…

The smart grid delivers electricity from producers to consumers using two-way digital technology and considers the involvement of the user. The implementation of smart grids should start at the consumer side using smart meters, control devices and a…

MIMO systems constitute a backbone of the fourth and fifth generations of wireless communication systems. The purpose of this paper is to introduce the involvement of conformal antenna arrays into MIMO systems. The Search Group Algorithm (SGA) is…

Electrical energy is considered to be the heart of modern civilization. Traditional electricalenergy generation approaches which usually rely on oil and its derivatives, produce different kinds of pollution in addition to being expensive to implement…

Traditional electrical grids rely heavily on Hydrocarbons. The latter turn out to be a significant cause of environmental damage, as well as being rapidly depleted. Remoteregions and settlements cannot benefit from this kind of electric energy as…

Fault Passage Indicators (FPIs); also named Faulted Circuit Indicators (FCIs), have been under development for the last 70 years including new capabilities to satisfy the needs of the distribution network operators. In order to improve system…
