Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - The Angle Of Arrival (AOA) estimation techniques are used to enable smart antennas to find the mobile user's location accurately. The optimization of some key parameters using MUSIC algorithm enables improved estimation of the AOA. The Minimum Mean Square Error (MMSE) is implemented in the algorithm of adaptive beam forming. The ability of enhancing the beam pattern (main lobe direction and the beam width) is achieved by choosing different values of relevant parameters. It has been found that increasing the number of array elements, increases the accuracy of beam-forming and more focusing of the beam is realized.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book addresses the design challenges in near-field wireless power transfer (WPT) systems, such as high efficiency, compact size, and long transmission range. It presents new low-profile designs for the TX/RX structures using different shapes of defected ground structures (DGS) like (H, semi-H, and spiral-strips DGS). Most near-field WPT systems depend on magnetic resonant coupling (MRC) using 3-D wire loops or helical antennas, which are often bulky. This, in turn, poses technical difficulties in their application in small electronic devices and biomedical implants. To obtain compact structures, printed spiral coils (PSCs) have recently emerged as a candidate for low-profile WPT systems. However, most of the MRC WPT systems that use PSCs have limitations in the maximum achievable efficiency due to the feeding method. Inductive feeding constrains the geometric dimensions of the main transmitting (TX)/receiving (RX) resonators, which do not achieve the maximum achievable unloaded quality factor. This book will be of interest to researchers and professionals working on WPT-related problems. 120 pp. Englisch.…
