This book addresses the design and analysis of different reflectarrays and transmitarray antennas to meet these requirements. A reflectarray is made up of an array of radiating elements that provide a preadjusted phasing to form a focused beam when it is illuminated by a feed, in a similar way to a parabolic antenna. Printed reflectarrays combine certain advantages of reflector antennas and phased arrays. The reflectarray antennas design in this work includes five antennas. The second part in this book discus five designs of the transmitarray. The first transmitarray is single layer...

This book addresses radiation, scattering and applications of plasma antennas.Plasma antenna is a special type of antenna which uses ionized noble gases (argon, neon, xenon...) as a conducting medium to perform similar to a metal which is usually used in traditional antenna. Plasma antennas have many advantages as their design permit electrical, rather than mechanical control for their radiation characteristics. They are light weight, reconfigurable, and can be energized, and de-energized in a fraction of a second. When a particular plasma antenna is de-energized, it does not affect the...
