The target of this publication is to introduce scholars and design-engineers to antenna layout and research utilizing the preferred advertisement electromagnetic software program FEKO. This e-book is basically meant for college kids 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 training engineers. The requirement for the readers of this booklet is to be conversant in the fundamentals of antenna idea; even though electric engineering scholars taking an introductory path in antenna engineering may also reap the benefits of this ebook as a supplementary textual content.

The key strengths of this ebook are as follows

* First, the fundamentals of antenna simulation should be offered in a close, comprehensible, and easy-to-follow process via research of the easiest varieties of radiators, i.e. dipole and loop antennas, in chapters 2 and three. it will construct the elemental wisdom a scholar would want with a view to make the most of antenna simulation software program mostly.

* moment, comparability among theoretical research and full-wave simulation result of FEKO are given for quite a few antenna forms, on the way to relief the readers with a greater realizing of the speculation, approximations and barriers within the theoretical research, and answer accuracy.

* 3rd, and of paramount significance, is the visualization of the antenna present distribution, radiation styles, and different radiation features which are made on hand via full-wave simulations utilizing FEKO. a formal research of the radiation features via those visualizations serves as a robust academic instrument to totally comprehend the radiation habit of antennas.

The advertisement electromagnetic software program FEKO is chosen for the simulations because of its various benefits and recognition. specifically, this software program presents a number of solvers that may be selected for a quick and effective research counting on the kind of antenna. furthermore, FEKO presents unfastened lecture room licenses to universities which can be utilized to simulate lots of the antenna configurations awarded during this book.

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

Here we will study the same quarter-wavelength monopole placed above a finite circular ground plane. 5l. Next we select the face of the ellipse and assign it as a ‘‘PEC’’. To efficiently perform the simulation here with the finite ground plane, we will use the physical optics solution option in FEKO. ’’ Next select both the monopole and ellipse and unite them. The geometry of this finite monopole antenna, along with the current distribution on the ground plane, is shown in Figure 2-17a. A contour plot showing the current distribution from the top view is given in Figure 2-17b.

A contour plot showing the current distribution from the top view is given in Figure 2-17b. As expected, the current is mostly concentrated at the center of the ground plane; thus, the current distribution and input impedance of this finite ground monopole will be similar to the infinite case studied earlier. The current distribution on the monopole and the input impedance as a function of frequency are given in Figure 2-18. 0 Z Y X Y X Y Z (a) X (b) Y Z X FIGURE 2-17 ¢ The quarter-wavelength monopole antenna above a finite ground plane: (a) 3D model in FEKO.

5l and height of 2l. 5l. The current distribution on the sphere is shown in Figure 2-29. The presence of this large scattering object implies that the radiation pattern of the dipole antenna will be distorted. The radiation pattern of the antenna is shown in Figure 2-30. Whereas some notable distortion in the pattern shape of a dipole is observed, the peak gain of the dipole is much larger because the cylinder is working as a reflector, which if designed properly can increase the gain of the antenna.
