Antenna Design With Fiber Optics / Edition 1

by Akhileshwar Kumar, A. Kumar

Overview

Fiber optic cables are an attractive alternative to conventional coaxial cables and waveguide beamforming networks because they offer larger bandwidth capabilities, immunity to electromagnetic interference, increased temperature tolerance, and smaller transmission losses.

This comprehensive book clearly explains the advantages of fiber optics and details the background, characteristics, fabrications, source components and design data necessary for applying optical fiber technology to the beamforming networks for state-of-the-art space and ground segment antennas. The application of fiber optic networks in various phased array antennas is also described, and problems related to the interface between optical and microwave components are explored in detail.

With 170 illustrations and 190 equations, this practical design guide is a unique and time-saving reference for antenna designers, system engineers, scientists, and managers.
