Frequency-Agile Antennas for Wireless Communications 2013

Mobile data subscriptions are expected to more than double and mobile
wireless traffic to increase by more than tenfold over the next few
years. Proliferation of smart phones, tablets, and other portable
devices are placing greater demands for services such as web browsing,
global positioning, video streaming, and video telephony. Many of the
proposed solutions to deal with these demands will have a significant
impact on antenna designs. Antennas with frequency agility are
considered a promising technology to help implement these new solutions.

This book provides readers with a sense of the capabilities of
frequency-agile antennas (FAAs), the widely diverse methods for
achieving tunability, the current achievable performance, and the
challenges still facing FAA designs. This resource explores the many
aspects of FAAs, including an examination of the metrics used to
evaluate their performance, a review of the most commonly used antenna
elements, an in-depth look at the wide variety of mechanisms for
achieving tunability, and a comprehensive survey of diverse examples of
FAA designs. The focus is on FAAs for wireless mobile communications
with applications including handsets, laptops, wireless
machine-to-machine communications, as well as larger, fixed designs such
as cellular base station antennas.
