ABSTRACT:
Provided is an antenna aligning apparatus for near-field measurement, which can perform alignment between a measurement target antenna and a probe antenna precisely by using an antenna pattern and detecting coordinates of the least error. The antenna aligning apparatus includes: a receiving antenna, a signal dividing means, a vertical polarization port, a horizontal polarization port, a first amplitude/phase detector, a second amplitude/phase detector, a coordinate determining means for, and a position adjuster.
