Phase error analysis of displaced-axis dual reflector antenna for satellite earth stations

, 2019
In a classical Cassegrain geometry, the sub-reflector partly blocks reflected rays from the main reflector. Feed antenna of the subreflector also blocks some of the radiated energy towards main reflector.
