Compact Antennas for Wireless Communications and Terminals: Theory and Design

Introduction

 

 

 

This publication covers microwave antennas and more specifically planar versions, which are the types of antenna preferred at microwave frequencies in modern integrated communication systems. We see variants of these in everyday life, hidden away in portable telephones, mobile phone base stations, electronic tags, or even portable computers. More generally, we see them in all applications requiring miniaturization and/or a fixed support structure, such as telephone casings. In terms of this publication, we are therefore not including reflector antennas, antenna arrays, or more generally directional antennas that occupy a surface or volume much greater than the wavelength.

Written by a collective of specialist engineers and research professors, this book is aimed at engineers and researchers who want to:

– understand the principles of planar and/or small volume antennas used in modern communication systems;

– comprehend the problems of design and manufacture;

– define the constraints and limitations presented by the antenna within the body of the communication system.

Chapter 1 deals with the physical characteristics of printed antennas (dielectric support, metallization), manufacturing techniques, and areas of application.

Chapters 2 and 3 describe the so-called transmission line and cavity models, respectively, of printed antennas. These two models provide complementary physical interpretations of the basic, usually rectangular geometry of antennas. These interpretations ...
