Abstract

For the purpose of generating a quasi-plane wave and realizing small-antenna pattern measurements in the 12 GHz band, a planar-waveguide array antenna consisting of 45 WRJ-120 rectangular waveguides with 57 longitudinal slots on the broad wall of each waveguide is fabricated and tested. The dimensions of the antenna are about 1100 mm×1300 mm×850 mm, including the waveguide-supporting frame, the feed network, and the antenna-supporting pedestal. As an example, the H-plane pattern measurement of a small pyramidal horn antenna is conducted in a small chamber at 12 GHz. The pattern obtained in the compact range is compared with the corresponding data obtained outdoors
