Review
'... this book is timely and could well provide third-to-fifth-year electronics students an added interest in their work but, more importantly, a means for qualified engineers in industry to update their knowledge in this specialised field. ... the book is well-printed and robustly bound with a colourful glossy cover. The print is easy-to-read on a good quality, crisp, paper and the numerous line drawings are excellent in quality.' Circuit World 'This book provides an excellent introduction to radio frequency engineering, using a straightforward and easily understood approach combined with numerous worked examples, illustrations and homework problems ... The book provides a broad coverage of RF systems, circuit design, antennas, propagation and digital techniques ... Material in the book has been carefully chosen to provide a basic training in radio frequency and a springboard for more advanced students ... Written for upper-level undergraduate courses, it also provides an excellent introduction to the subject for graduate students, researchers and practicing engineers.' Iasi Polytechnic Magazine

Review
"His approach gives readers a strong theoretical foundation by using a minimum of mathematics and numerous examples, illustrations, and homework problems. This well-written book is intended for upper-level electrical engineering undergraduates, graduate students, researchers, and practicing engineers. Recommended for libraries associated with electrical engineering academic programs. Highly recommended." F.A. Cassara, Polytechnic University, CHOICE
