Phased-array antenna employing an electrically controlled lens

摘要

A phased-array antenna in which transmitting energy from a primary feed system is radiated through free space as a primary wave to a plurality of first radiator elements, where they are received, and conducted over a plurality of phase shift elements, which may be electronically controlled, and which convert the primary wave into a planar wave and additionally effect a desired beam deflection, with such waves being radiated by a plurality of second radiator elements, in the form of a planar wave with received energy passing in the opposite direction along the same path, in which a second primary feed system is disposed at the second radiator elements and also supplied with transmitting energy which is radiated through free space, as a primary wave, to the second radiator elements where it is received, conducted over said phase shift elements and radiated by the first radiator elements in the form of a planar wave.
