Antenna analysis and design using FEKO electromagnetic by Atef Z. Elsherbeni

By Atef Z. Elsherbeni

The target of this booklet is to introduce scholars and design-engineers to antenna layout and research utilizing the preferred advertisement electromagnetic software program FEKO. This e-book is essentially meant for college students operating within the box of antenna research and layout; but the wealth of hands-on layout examples awarded during this book―along with simulation details―also makes it a useful reference for working towards engineers. The requirement for the readers of this ebook is to be acquainted with the fundamentals of antenna conception; even if electric engineering scholars taking an introductory path in antenna engineering may also make the most of this booklet as a supplementary textual content.

The key strengths of this ebook are as follows
* First, the fundamentals of antenna simulation might be provided in an in depth, comprehensible, and easy-to-follow method via research of the best varieties of radiators, i.e. dipole and loop antennas, in chapters 2 and three. it will construct the elemental wisdom a scholar would wish as a way to make the most of antenna simulation software program in most cases.
* moment, comparability among theoretical research and full-wave simulation result of FEKO are given for a number of antenna forms, so as to reduction the readers with a greater knowing of the idea, approximations and boundaries within the theoretical research, and answer accuracy.
* 3rd, and of paramount value, is the visualization of the antenna present distribution, radiation styles, and different radiation features which are made to be had via full-wave simulations utilizing FEKO. a formal research of the radiation features via those visualizations serves as a strong academic instrument to totally comprehend the radiation habit of antennas.

The advertisement electromagnetic software program FEKO is chosen for the simulations because of its quite a few merits and recognition. particularly, this software program offers a number of solvers that may be selected for a quick and effective research reckoning on the kind of antenna. in addition, FEKO presents loose lecture room licenses to universities which can be utilized to simulate lots of the antenna configurations awarded during this book.

FEKO simulation records can be found to teachers who undertake the publication for his or her direction or execs who've bought the publication. Please touch The IET for additional information
