Available in PDF, EPUB and Kindle. Book excerpt: In the first chapter there is given a basis and account of the method of measurement of basic parameters of shf antennas, typical circuits applied here and also methods of processing and estimating error of measurements. In the second chapter seven laboratory projects of antenna practical work are described. The practical work permits us to subject to graphic experimental proof a series of very important theoretical propositions expounded in the course on shf antennas; to illustrate the method of measurements of parameters of antennas with practical examples; to acquaint students with the design and certain methods of engineering calculation of basic types of shf antennas. Description of every practical project contains information on designing the proper laboratory installation, assignment for conducting experiments and calculations, and also a list of materials which should be presented in the report on the finished project. Selection of problems for practical work and the character of assignments are aimed at development in students of a desire for independent investigation. Everywhere where possible, comparison of theory with experiment and estimation of its accuracy are required. In the third chapter there is given a description of a series of samples of typical equipment applied during shf antenna measurements. This facilitates home preparation of students for doing assignments of antenna practical work and can serve as a brief reference book on frequently used equipment. (Author).

Download or read book Advancements in Antenna Measurement written by Martin Krchňák and published by Springer Nature. This book was released on 2024-01-19 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a pioneering exploration of a new form of high-frequency attenuation chamber that has the potential to revolutionize antenna measurement techniques. The authors present an innovative concept that leverages the classical principle of changing the polarization of radio waves, eliminating the need for traditional non-reflection chambers. By analyzing experimental results and searching for the optimal shape and composition of a depolarization panel, this monograph provides valuable insights into creating a non-reflective environment for accurately measuring the directional properties of antennas. The book delves into the methodology of frequency analysis, optimization of the depolarization panel, and the creation of a measuring workplace using this panel. It highlights the crucial attenuation phenomenon of suppressing cross-polarization coupling between transmitting and receiving antennas, enabling antenna measurements in any laboratory environment. With its promising results and practical applications in antenna technology, this publication offers a compelling and cutting-edge approach to antenna measurement that will captivate researchers, engineers, and professionals in the field.

This book was released on 2014-01-23 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this work, new concepts of body-matched antennas for microwave medical applications were developed, where the antennas are placed directly on or in the human body. Two types of antennas were designed - on-body matched antennas for diagnosis and implantable antennas for data telemetry with the main focus of miniaturization yet maintained a high radiation performance. The applicability of the antennas was verified using a medical imaging system for the detection of hemorrhagic stroke.

This book was released on 2020-12-08 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to progress in the development of communication systems, it is now possible to develop low-cost wearable communication systems. A wearable antenna is meant to be a part of the clothing or close to the body and used for communication purposes, which include tracking and navigation, mobile computing and public safety. Examples include smartwatches (with integrated Bluetooth antennas), glasses (such as Google Glass with Wi-Fi and GPS antennas), GoPro action cameras (with Wi-Fi and Bluetooth antennas), etc. They are increasingly common in consumer electronics and for healthcare and medical applications. However, the development of compact, efficient wearable antennas is one of the major challenges in the development of wearable communication and medical systems. Technologies such as printed compact antennas and miniaturization techniques have been developed to create efficient, small wearable antennas which are the main objective of this book. Each chapter covers enough mathematical detail and explanations to enable electrical, electromagnetic and biomedical engineers and students and scientists from all areas to follow and understand the topics presented. New topics and design methods are presented for the first time in the area of wearable antennas, metamaterial antennas and fractal antennas. The book covers wearable antennas, RF measurements techniques and measured results in the vicinity of the human body, setups and design considerations. The wearable antennas and devices presented in this book were analyzed by using HFSS and ADS 3D full-wave electromagnetics software.
