Overview

This book describes and provides design guidelines for antennas that achieve compactness by using the slot radiator as the fundamental building block within a periodic array, rather than a phased array. It provides the basic electromagnetic tools required to design and analyse these novel antennas, with sample calculations where relevant. The book presents a focused introduction and valuable insights into the relevant antenna technology, together with an overview of the main directions in the evolving technology of compact planar arrays.   While the book discusses the historical evolution of compact array antennas, its main focus is on summarising the extensive body of literature on compact antennas. With regard to the now ubiquitous slot radiator, it seeks to demonstrate how, despite significant antenna size reductions that at times even seem to defy the laws of physics, desirable radiation pattern properties can be preserved. This is supported by an examination of recent advances in frequency selective surfaces and in metamaterials, which can, if handled correctly, be used to facilitate physics-defying designs.   The book offers a valuable source of information for communication systems and antenna design engineers, especially thanks to its overview of trends in compact planar arrays, yet will also be of interest to students and researchers, as it provides a focused introduction and insights into this highly relevant antenna technology.

Author Information

​Alan J. Sangster received a B.Sc. in Electrical and Electronic Engineering in 1963, an M.Sc. in 1964, and a Ph.D. in 1967, all from the University of Aberdeen in Scotland. His research interests have been in the areas of microwave antennas, mm-wave sensing, electrostatically driven micromotors and microactuators, electromagnetic levitation, medical applications of microwaves, microwave propagation in geological strata, satellite communications at microwave frequencies, and the numerical solution of electromagnetic radiation and scattering problems. He is the author of over 230 papers on these topics. Professor Sangster spent four years with Ferranti plc, Edinburgh, Scotland, pursuing research into wide-band travelling wave tubes, and three years with Plessey Radar Ltd., Cowes, U.K., investigating and developing microwave devices and antennas for microwave landing systems and frequency scanned radar systems. Since 1972, he has been with the Heriot-Watt University, Edinburgh, where he became a full Professor of Electromagnetic Engineering in 1989. He retired in 2006, but continues to act in a professorial capacity as a consultant to industry on microwave antennas and microwave component design. He is a Chartered Electrical Engineer, a Fellow of the Institution of Engineering Technology (U.K.), and a Member of the Electromagnetics Academy (U.S.A.).
