Abstract
Planar near-field scanning and a hologram type of compact antenna test range (CATR) are used to determine the radiation characteristics of a novel 40 GHz planar antenna. The results are compared with those obtained from a far-field measurement. The near-field scanning method works very well, and as a result, a complete three dimensional radiation pattern is obtained as well as the aperture distribution of the antenna under test (AUT). The same antenna was also measured with a hologram CATR. Despite the fact that the used hologram CATR had a design error making the quiet-zone too small, it was demonstrated that the hologram CATR method is feasible at long millimeter wavelengths.
