| NOTAS: | "Phased array antennas consist of multiple stationary antenna elements, which are fed coherently and use variable phase or time-delay control at each element to scan a beam to given angles in space. The primary reason for using arrays is to produce a directive beam that can be repositioned (scanned) electronically. This text discusses array design issues in eight chapters: phased arrays in radar and communication systems; pattern characteristics of linear and planar arrays; pattern synthesis for linear and planar arrays; patterns of nonplanar arrays; elements, transmission lines, and feed architecture for phased arrays; summary of element pattern and mutual impedance effects; array error effects; and special array feeds for limited field-of-view and wide-band arrays." |
