Название: Metamaterials for Antenna Applications Автор: Amit K. Singh, Mahesh P. Abegaonkar Издательство: CRC Press Год: 2022 Страниц: 215 Язык: английский Формат: pdf (true) Размер: 41.0 MB
The book presents an engineering approach for the development of metamaterials and metasurfaces with emphasis on application in antennas. It offers an in-depth study, performance analysis and extensive characterization on different types of metamaterials and metasurfaces. Practical examples included in the book will help readers to enhance performance of antennas and also develop metamaterial-based absorbers for a variety of applications.
Metamaterials are artificially engineered homogeneous materials that exhibit unusual electromagnetic (EM) properties not existing in nature. These artificially engineered materials have the capability to modify incoming EM waves in many ways that are beyond naturally existing bulk materials. The Greek word “meta” means beyond, and the term “metamaterial” is used to describe such class of materials which have properties beyond those of existing materials.
Miniaturized antennas are the major requirement for microwave monolithic integrated circuits to provide proper communication solution. The desire to incorporate multiple frequency bands of operation into personal communication devices has led to much research on reducing the size of antennas while maintaining adequate performance. In addition, antennas and RF front ends, which form the integral part of a wireless system, have not been exempted from the demand for miniaturization. The advancements in the field of material sciences, antenna design techniques, Surface Mount Device lumped components and fabrication technologies have led to the development of many pathways to achieve miniaturization. This in turn has paved the way for researchers in antenna miniaturization to engage actively in adding new dimensions to the field. Due to various technological advancements, there are many antenna miniaturization techniques known now, and some of them will be discussed later.
