More Book Details

Description of the Book:

Integration of a solid-state transistor oscillator with a radiative element has many advantages: it eliminates the feed network, replaces the expensive waveguide transition, reduces the size of the antenna system, and provides active impedance matching. Active devices also offer promise for optical control of beam steering antenna arrays. The objective of this thesis is to determine the physical characteristics of an active antenna and understand its operational principles
