Covering a wide range of application areas, from wireless communications and navigation, to sensors and radar, this practical resource offers you the first comprehensive, multidisciplinary overview of radio engineering. You learn important techniques to help you with the generation, control, detection and utilization of radio waves, and find detailed guidance in radio link, amplifier, and antenna design. The book approaches relevant problems from both electromagnetic theory based on Maxwell 's equations and circuit theory based on Kirchoff's and Ohm's laws, including brief introductions to each theory. Featuring in-depth discussions on passive transmission lines and components, RF circuits, and fundamentals of antennas and radio wave propagation, this essential reference helps you fully understand and design radio systems, taking into account noise and modulation considerations. What's more, the book includes a review of biological effect and safety standards. This unique volume also serves as an excellent text for undergraduate- and graduate-level electrical engineering courses in this area.
