Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Wireless communications have demand for wireless device of light weight, small size, having low energy consumption and of more practicability. The microstrip antenna is the best choice that fulfills the basic requirements of wireless communication device i.e. antenna should be relatively cheap, light weight, robust, easy to manufacture and with a minimum impact on environment. The microstrip patch antennas are of narrow band width because of which the design parameters of patch antenna must be determined with high precision. So, with in a fabrication process of such kind of antennas, Artificial Neural Networks (ANNs) based models trained with experimental/generated data of same class, previously collected, can preliminary estimate the design parameters, reducing the number of real prototypes to be constructed, saving time and resource. The results obtained using, Artificial Neural Networks (ANN) techniques are close to experimental results and Electromagnetic computer (EMC) simulating tools. Therefore to design Microstrip patch antennas for wireless communication, Artificial Neural Network techniques can be embedded in computer aided design (CAD) system 60 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -From this book it has been also observed that tapers in both wave launching and free space radiating edges are useful in simultaneous impedance matching and improvement of the radiation pattern. The introduction of pyramidal taper in the front radiating face with adjustable properties (length and base area of the introduced pyramidal taper section) can give similar directive beam without undesirable increase in length and at the same time it shows dual frequency operation. An appropriate approach of truncation in the front radiating edge with adjustable properties (length and base area of the truncated pyramidal hollow section) can give improved directive beam without undesirable increase in length and at the same time huge improvement in bandwidth and impedance matching. For the limitation of fabrication facilities, this truncated front truncated pyramidal dielectric slab antenna could not be studied experimentally so far. Even better performance may be obtained by stepped truncation of the radiating aperture creating an array of additional apertures. All these give our proposed antenna competitive advantage for trans-receiver applications over standard dielectric slab antennas. 52 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book starts with a description of this historical background and discussion on the theoretical analysis techniques for dielectric radiators. An overview of the Finite Elements Method (FEM), which has been applied extensively in the thesis, is also presented thereafter. In this thesis, impedance and radiation characteristics of various different dielectric radiators e.g. dielectric slabs, rods, loaded dielectric slab, modified aperture dielectric solid slab, cones and horns etc. are thoroughly investigated for their optimal performances. Consequent optimal designs for parameters like bandwidth, gain etc. are developed. Modifications to the basic antenna structure are proposed in the form of insertion of reactive loading (using shorting pins) and changing the radiating apertures through tapering and truncation. All these are performed to improve gain and bandwidth characteristics and /or minimizing feed reflections so as to enhance the antenna performance. 52 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -There are always more aspects that can be investigated than what is presented. Here also, there are some aspects of both the new antenna and parameter calculation that can be extended. The new designed presented in this thesis open up the scopes for high gain, wide band and miniaturized microstrip patch antennas for wireless applications. The controlling tools like slot length, width, angle can be further exploited to achieve tunable parameters of micros trip patch antenna as required in application like medical imaging, cancer detection and smart wireless environment. The idea of implementing artificial neural networks in parameters calculation of microstrip patch antenna invites further exploration of the technique to reduce the complexities in the antenna design and analysis. Integration with optimization techniques such as Genetic algorithm, PSO etc may enhance the efficiency in terms of computational time and accuracy to make the ANN method of antenna design more acceptable especially for the application areas like bio-medical and smart wireless environment. 72 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -From this book it has been also observed that the methods solves for the field sources (currents and charges). These sources can be either physical sources, or mathematical (equivalent) sources introduced through various electromagnetic field theorems. In the numerical analysis, the electromagnetic fields, or the related potentials, are expressed in terms of these sources, usually through the Lorentz potentials. The expressions are integral forms, where the sources appear under some integrals, multiplied by appropriate functions, which are referred to as kernels. For example, for fields in a vacuum, the kernel for the Lorentz potentials is the free-space Green's function. On the other hand, certain equations are imposed based on the boundary conditions or constitutive relations. The boundary conditions relate tangential and normal components of the field vectors at a surface of discontinuity. For example, on the surface of a perfectly conducing body, the tangential component of the electric field vanishes. 56 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -De este libro también se ha observado que los métodos resuelven las fuentes de campo (corrientes y cargas). Estas fuentes pueden ser fuentes físicas, o fuentes matemáticas (equivalentes) introducidas a través de varios teoremas de campo electromagnético. En el análisis numérico, los campos electromagnéticos, o los potenciales relacionados, se expresan en términos de estas fuentes, normalmente a través de los potenciales de Lorentz. Las expresiones son formas integrales, donde las fuentes aparecen bajo unas integrales, multiplicadas por funciones apropiadas, que se denominan kernels. Por ejemplo, para los campos en el vacío, el núcleo de los potenciales de Lorentz es la función de Green del espacio libre. Por otro lado, se imponen ciertas ecuaciones basadas en las condiciones de contorno o relaciones constitutivas. Las condiciones de contorno relacionan las componentes tangenciales y normales de los vectores de campo en una superficie de discontinuidad. Por ejemplo, en la superficie de un cuerpo perfectamente conductor, la componente tangencial del campo eléctrico desaparece. 52 pp. Spanisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Dans ce livre, il a également été observé que les méthodes résolvent les sources de champ (courants et charges). Ces sources peuvent être soit des sources physiques, soit des sources mathématiques (équivalentes) introduites par divers théorèmes de champ électromagnétique. Dans l'analyse numérique, les champs électromagnétiques, ou les potentiels associés, sont exprimés en fonction de ces sources, généralement par les potentiels de Lorentz. Les expressions sont des formes intégrales, où les sources apparaissent sous certaines intégrales, multipliées par des fonctions appropriées, que l'on appelle des noyaux. Par exemple, pour les champs dans le vide, le noyau pour les potentiels de Lorentz est la fonction de Green de l'espace libre. D'autre part, certaines équations sont imposées sur la base des conditions aux limites ou des relations constitutives. Les conditions aux limites concernent les composantes tangentielle et normale des vecteurs de champ à une surface de discontinuité. Par exemple, à la surface d'un corps parfaitement conducteur, la composante tangentielle du champ électrique disparaît. 52 pp. Französisch.
