Abstract
Hologram-based compact antenna test range (CATR) is a potential method
for testing large antennas at submillimeter wavelengths. This paper
describes testing of a 1.5-m single offset parabolic reflector antenna
with a 3-m-diameter hologram-based CATR. This is the first time such a
measurement is carried out at submillimeter wavelengths. The antenna
tests were done in a CATR that was specifically designed and constructed
for these tests. The measured radiation pattern at the frequency of 322
GHz is presented. The measured pattern corresponds reasonably well to
the simulated pattern of the antenna. The effect of the quiet-zone field
nonidealities on the measurement results and the reasons for the
discrepancies in the measured antenna beam are discussed.
