Full Description
Switched parasitic antennas have recently become of significant interest to professionals in the telecommunications industry. This first-of-its-kind book introduces R&D antenna and communications network engineers to the basic concepts and wide range of potential applications of switched parasitic antennas, including smart antennas for wireless communications. Ths book's clear, detailed discussion of design rules for both wire and patch antenna structures, together with their circuit requirements, gives practitioners the knowledge they need to successfully design and implement low-cost, small, switched parasitic antennas for a variety of uses.
