Abstract :
It becomes increasingly difficult to obtain far-field measurements for large millimetre wave antennas at higher frequencies due to the required large distance between the antennas. A hologram compact antenna test range (CATR) is used to determine the radiation characteristics of a 39 GHz planar antenna in a small facility. The results are compared with those obtained from planar near-field scanning and conventional far-field measurements
