Compact and sturdy long focal antenna, designed to be bench tested and mounted on a satellite

摘要

The antenna (2) has a paraboloid reflector (5) including an active surface oriented opposite to a supporting structure (3). A radial fixation rod (6) is connected to a deployment arm (8) of the reflector, and is directed towards the top of the supporting structure. The deployment arm is connected to a secondary support (10) by an articulation (9) that is motorized by a step-by-step electrical motor. The arm is positioned between the reflector and the supporting structure in a stored position of the antenna. The reflector is plated against the supporting structure.
