The present invention relates to a phase shifter structure of a multi-polarization antenna. The phase shifter structure of a multi-polarization antenna comprises a plurality of phase shifters each comprising a power feeding unit, a base substrate on which an arc-shaped pattern is formed, and a variable phase shifter mounted on the center of the pattern on the substrate to be rotated about a shaft. Characteristically, the phase shifter structure of a multi-polarization antenna comprises: base substrates stacked on top of each other; a synchronization means to mount an upper and a lower variable phase shifter on each other to synchronously drive the upper and the lower variable phase shifter; and a drive unit to supply a rotational force to one of the variable phase shifters. Preferably, the drive unit supplies power in a push method instead of a gear method. According to the present invention, space efficiency of the phase shifters is excellent, and operation of the upper and the lower phase shifter is accurate and stable. |
