Frequency-agile antennas (FAAs), a subset of active integrated antennas (AIAs), show great promise for being able to handle the ever increasing volume of mobile wireless traffic. Designed to have a dynamically tunable frequency, they will be able to productively handle data transmission from handsets, laptops and wireless machine-to-machine communications. After a general description of antenna elements and frequency tuning techniques, the book goes on to explore FAA designs based on mechanical tuning techniques, tunable substrates, and continuous and discrete tuning with integrated devices. Along the way it examines the metrics used to evaluate FAAs. Larger fixed designs, such as cellular base station antennas also receive some attention. The book closes with a list of acronyms and symbols used throughout. Annotation ©2014 Book News, Inc., Portland, OR (booknews.com)
