A class of dynamic holographically addressed millimeter wave antennas becomes possible by combining the principle of holography with the notion of microwave transparency produced by excess carrier generation in semiconductor panels or preferably by reflectivity modulation of an interferometric structure consisting of a dielectric air gap metal structure. The theory of operation of the holographically addressed antenna is presented together with a discussion of possible methods for its implementation. The advantages of using a microwave Kinoform for this purpose are also pointed out.
