Reflecting a growing interest in phased array antenna systems,stemming from radar, radio astronomy, mobile communications andsatellite broadcasting, Array and Phased Array AntennaBasics introduces the principles of array and phased arrayantennas. Packed with first-hand practical experience andworked-out examples, this is a valuable learning tool and referencesource for those wishing to improve their understanding of basicarray antenna systems without relying heavily on a thoroughknowledge of electromagnetics or antenna theory.
* Features a general introduction to antennas and explains thearray antenna principle through discussion of the physicalcharacteristics rather than the theory
* Explores topics often not covered in antenna textbooks, such asactive element pattern, array feeding, means of phase changing,array antenna characterisation, sequential rotation techniques andreactively loaded arrays
* Guides the reader through the necessary mathematics, allowingthem to move onto specialist books on array and phased arrayantennas with a greater understanding of the topic
* Supported by a companion website on which instructors andlecturers can find electronic versions of the figures
An ideal introduction for those without a background inantennas, this clear, concise volume will appeal to technicians,researchers and managers working in academia, government,telecommunications and radio astronomy. It will also be a valuableresource for professionals and postgraduates with some antennaknowledge.
