Description

As a result of recent growth of the wireless market, research and development in antenna technology is growing at a fast pace. New emerging technologies include antennas for cellular mobile communications, vehicle mounted antennas and those for mobile satellite communications.This text is intended to introduce new engineers and undergraduates to the topic of antennas. It is a well-paced, low level introduction to the subject that does not require previous knowledge of electromagnetic theory. In addition, the step by step approach to maths is ideal for those who do not have a good mathematical background. It provides a good introduction to the subject without being overly detailed and includes some non-core subjects to give the student a good overview of techniquesshow more

Back cover copy

This new text is an introduction for undergraduates and engineers and is designed to give the reader a reasonably paced introduction to the theory that underpins antenna design techniques. As a result of recent growth of the wireless market, research and development in antenna technology is proceeding at a fast pace. New emerging technologies include antennas for cellular mobile communications, vehicle mounted antennas and those for mobile satellite communications. Key features coverage of the fundamentals of antennas a step by step simplified mathematical approach basic antenna matching techniques antenna systems and related characterisation methods end of chapter problems includes a list of principle symbols and a glossaryThis text is aimed at undergraduates in electrical and electronic engineering and physics, and is suitable for courses in electromagnetics, antenna theory and design, antennas and radar, radio engineering, mobile communications, telecommunications courses. It will also be suitable for professional engineers requiring an introduction to the subject and the techniques. Professor Vincent Fusco has a Chair in High Frequency Electronic Engineering at Queen's University, Belfast and is head of high frequency research. He has published extensively in international refereed journals and conferences.show more
