A novel approach to scanning antennas design
Keywords:scanning antenna, synthetic aperture, radiator, elctromechanical scanning, MEMS
AbstractA new concept for design of scanning antennas is suggested. The concept is based upon a combination of a single radiating element movement with antenna aperture synthesizing. The radiator movement may be either real or virtual one. In turn, the latter may be either mechanical or electronic one. In the paper, the case of electromechanical motion is preferably considered. Various realizations of real and virtual movements of the radiator are shortly described. Examples of the concept implementing are presented. Advantages and drawbacks of the concept are briefly discussed.
