Abstract

Computer-generated holograms (diffractive elements) can be used for shaping submillimeter-wave beams, e.g., for producing a plane wave in a compact space. An amplitude hologram has proved to be a feasible alternative as a focusing element in a compact antenna test range (CATR) at submm-wavelengths. In a recent study, we have designed and constructed a compact antenna test range for 322 GHz and measured the ADMIRALS representative test object, which is a 1.5-meter offset paraboloid antenna. In another study, the feasibility of a phase hologram based RCS (radar cross section) range has been verified with simple test objects.
