Reflection structure for optimizing phase mutation of lateral array antenna of interferometer

The utility model provides a reflection structure for optimizing phase mutation of a lateral array antenna of an interferometer, and belongs to the field of antenna structures. The antenna comprises a bottom plate, a reflecting plate and a frequency band antenna, the base plate and the reflecting plate are correspondingly connected at intervals, a plurality of through holes which are uniformly arranged at intervals are formed in the reflecting plate, the plurality of frequency band antennas are mounted on the base plate, the plurality of frequency band antennas are nested in the through holes, and meanwhile, the upper end surfaces of the frequency band antennas are flush with the end surface of the reflecting plate; according to the whole device, mutual coupling between the antennas and the multipath effect formed by antenna installation accessories are reduced through the reflecting plate, the upper end face of the frequency band antenna is flush with the end face of the reflecting plate, and the influence o
