2016 10th European Conference on Antennas and Propagation (EuCAP).
The development of a slimline Q/V-band feed system engineering model (EM) suitable for multi-beam antenna applications and feed spacing of around 26mm is described. This new feed product will extend telecoms satellite capacity by using Q/V-band for g
