An accurate and efficient numerical model is developed to simulate the far field of an antenna under test (AUT) measured in a Compact Antenna Test Range (CATR), on the basis of the known quiet zone field and the theoretical aperture...

ESA’s Compact Antenna Test Range at ESTEC has been relocated which has given the chance to improve the alignment of the reflectors. Based on measurements of the reflector surfaces the best-fit positions and orientations of the reflectors have been determined....

Shaped reflectors form one of the cornerstones of satellite telecommunications today, and have in all but a few cases replaced the array-fed parabolic reflector antennas for contoured beam generation. The evolution started in the 1990’es with the advent of efficient...

The possibility of employing the same spacecraft at several orbital locations, changing the coverage region, and compensating for varying weather conditions are the main reasons why reconfigurable antennas for contoured beam generation can provide significant advantages in satellite communications.
