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 will be a well-paced, low level introduction to the subject. This text 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 techniques.

Features

" Uses a series of simple explanations based on undergraduate physical concepts (such as the physics of motion, Coulombs, and Amperes Law) to construct a framework which leads to the development of the radiation characteristics of basic antenna types

" The author uses intermediary steps in the elaboration of key concepts to facilitate a better understanding of the physical principles associated with antennas - makes the text accessible to those who have not studied advanced vector calculus

" Details the operation of arrays of basic wire antennas in order to enhance their collective radiation characteristics

" Uses a logical development of the precise technical terminology used by antenna designers when specifying or quantifying antenna behaviour

" Includes coverage of issues such as impedance matching terminology and practice - only assumes a knowledge of 1st year undergraduate circuit theory

" The final chapter provides a brief introduction to the key antenna structures deployed widely in industry, as well as a summary of some modern antenna types which are currently occupying research literature - including Fractal antennas, the Planar Inverted F antenna and the Reflectarray
