Download Frequency-Agile Antennas for Wireless Communications (Artech by Aldo Petosa PDF

By Aldo Petosa

cellular facts subscriptions are anticipated to greater than double and cellular instant site visitors to extend by way of greater than tenfold over the following couple of years. Proliferation of shrewdpermanent telephones, drugs, and different moveable units are putting higher calls for for providers corresponding to internet searching, international positioning, video streaming, and video telephony. a number of the proposed suggestions to accommodate those calls for may have an important effect on antenna designs. Antennas with frequency agility are thought of a promising know-how to assist enforce those new solutions.

This e-book presents readers with a feeling of the functions of frequency-agile antennas (FAAs), the generally different equipment for attaining tunability, the present conceivable functionality, and the demanding situations nonetheless dealing with FAA designs. This source explores the numerous facets of FAAs, together with an exam of the metrics used to guage their functionality, a assessment of the main wide-spread antenna parts, an in-depth examine the big variety of mechanisms for attaining tunability, and a entire survey of numerous examples of FAA designs. the point of interest is on FAAs for instant cellular communications with purposes together with handsets, laptops, instant machine-to-machine communications, in addition to greater, mounted designs akin to mobile base station antennas.
