Ground test of array-fed reflector antennas for ETS-VIII

摘要

With regard to the ground test on large deployable reflector antennas of the Japanese Engineering Test Satellite VIII, a new test method of verifying reflector antennas with reduced aperture area was proposed. Analytical study showed several radiation beams are retainable without serious degradation by the proposed method. Through conducted antenna test, we have confirmed adequateness of an analytical procedure of multi-module reflector antennas and a design method of array-fed reflector antennas and also operational normality of a multi-module reflector and feed arrays.
