Abstract
An amplitude hologram is a novel alternative as the focusing element in a CATR (compact antenna test range) at submm-wavelengths. The amplitude hologram can be manufactured using printed circuit board technology. However, for tests of high-gain antennas, the required size of the hologram may be several square meters. Details concerning manufacture of the holograms and the subsequent tests are discussed. Potential methods for manufacturing and joining of holograms are identified and measured results at 310 GHz are shown.
