With the electronic scanning antenna being plane and having a power distribution that is symmetrical in amplitude and in phase, the device has means positioning a malfunctioning phase-shifter and its symmetrical phase-shifter in supplementary phase states. Application notably to landing systems requiring high precision for the aiming of the beam in free space.
