Reconfigurable Compact Cross Patch Antenna for Switchable Polarization (Paperback)

Antennas are necessary and vital components of communication and radar systems, but sometimes their mobility to adjust to new operating scenarios can limit system performance. Reconfigurable antennas can adjust with changing system requirements or environmental conditions and provide additional levels of functionality that may result in wider instantaneous frequency bandwidths, more extensive scan volumes and radiation patterns with more desirable side lobe distributions. Their agility and diversity created new horizons for different types of applications especially in cognitive radio, Multiple Input Multiple Output Systems, satellites and many other applications. Reconfigurable antennas satisfy the requirements for increased functionality, such as direction finding, beam steering, radar, control and command, within a confined volume.

Radiation and Scattering from Plasma Antennas and Applications (Paperback)

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 nearby elements and allowing other antennas to transmit or receive without any effect due to the notenergized plasma antenna.For plasma to be excited, ionization is necessary. Plasma density usually refers to the electron density, the number of free electrons per unit volume. The plasma is a kind of a reconfigurable dispersion material with different conducting and dielectric properties. The dispersion material properties can be reconstructed with different electron densities and collision frequencies. So, the radiation characteristics of plasma antenna are controlled using such factors Radiation and Scattering from Plasma Antennas and Applications (Paperback)
