Abstract :
A millimeter-wave power splitter/combiner working on the principles of holography is presented. A hologram which stores the holographic image of a number of beams has the function of a power splitting element. An input beam to this hologram causes the recorded beams to be reconstructed, which is none but a high-efficiency process of beam splitting. A measured efficiency of 93%, high isolation, and a relatively large bandwidth are demonstrated.
