Condition: Hervorragend. Zustand: Hervorragend | Sprache: Deutsch | Produktart: Bücher | Um den Energiebedarf der Gesellschaft zu decken, werden in jüngster Zeit nicht-konventionelle Energiequellen von der Forschung erforscht. Energie aus der Umgebung (z. B. Sonne, Wind und Gezeiten) ist in großem Umfang verfügbar, und es werden… groß angelegte Technologien entwickelt, um sie effizient zu nutzen. Das Ernten von Erdenergie kann in diesem Szenario eine wichtige Rolle spielen. In diesem Buch wird eine neuartige Idee zur Gewinnung von Erdenergie vorgestellt, bei der Antennensensoren als nächtliche Energiesammler eingesetzt werden. In dieser Arbeit wurden verschiedene Antennen verwendet, um die Infrarotstrahlung, die die Erde während der Nachtstunden abstrahlt, zu erfassen, was eine umweltfreundliche Energielösung für die Gesellschaft sein kann.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In recent days, to meet the energy requirement of society, non-conventional energy resources are being explored by research fraternity. Large-scale ambient energy (example solar, wind and tide), is most widely available and large-sc…ale technologies are being developed to efficiently capture it. Earth Energy harvesting can play an important role in this scenario. This book presents a novel idea of harvesting earth energy using antenna sensor as night time energy harvester. In this work, various antennas have been used to capture the infrared radiations that the earth radiates during night hours.This can be an environment friendly energy solution for the society. 88 pp. Englisch.

Paperback. Condition: new. Paperback. This book presents a triangular-notched wideband antenna for wearable wireless body area networks (WBAN) and Global Positioning System (GPS) applications. The compact antenna (0.487l0 0.581l0 ) is fabricated on a low-cost jeans substrate and features a broad rectangular slot for improved gai…n and compressed reduced ground for a wide operating bandwidth (1.47-2.68 GHz). The triangular notches in the patch increase the electrical length of the patch and the resulting fundamental mode TM10 (1.51 GHz), and control impedance matching. The antenna achieves bidirectional radiation patterns a 6.20 dBi peak gain, and 98% efficiency. When a large slot (Lslot Wslot ) is cut in a patch, it interrupts the standard TM current distribution and creates its resonance at 2.51 GHz, which overlaps the higher order mode of the patch (slot resonance mode TM02 ) and resulting in a "wideband effect" (1.47-2.68 GHz bandwidth). The antenna bending exhibited stable S11 and gains. The human body phantom results ON-body and OFF-body Specific Absorption Rate (SAR) values of 1.24 W/kg (wrist) and 1.06 W/kg (chest) at 100 mW input power, within IEEE/IEC limits of 2 W/kg for 10 g tissue. The performance parameters were validated using SMA 1075X and an anechoic chamber. The antenna had an average efficiency of 88% and a peak gain of 6.20 dBi. The proposed approach introduces an antenna size-reduction method. At 2.45 GHz, the antenna was 8.96% smaller than a typical antenna. The same antenna can be used for boy-centric medical applications if the specific absorption rate (SAR) and bending impact are carefully measured.The antenna demonstrated the stability of the effectiveness parameter against bending. Compared to the IEEE standard SAR value of 2 W/kg, the antenna's averaged SAR value with 10 g tissues on the human body, wrist, and chest was 0.979 W/kg, 1.02 W/kg, and 1.26 W/kg, respectively. By modifying the input power levels in the future, the SAR value at the thigh, which is slightly higher than the standard value, could be reduced. The proposed antenna is an ideal solution for low-power MMIC/MIC transmitters and receivers in Wi-Fi, WLAN, WiMAX, Bluetooth, and energy-harvesting. This item is printed on demand.
