Fast Measurement of Single-Cut Far-Field Patterns at Quasi-Far-Field Distance for Linear Antenna Array of Any Polarization

Corrected method for fast measurement of single-cut Far-Field (FF) pattern at Quasi-Far-Field (QFF) distance linear antenna array any polarization by two orthogonal measurements has been proposed in this paper. The analytical equations were deduced based on cylindrical wave expansion (CWE). required don't need to satisfy the FF condition under test (AUT), only region small dimension AUT, so it is another large dimension, which makes process same as measurements. Therefore, introduced especially applicable arbitrary polarized antennas with one large, and small. 45° linearly circularly simulated prove method, corrected results using presented algorithm are consistent theoretical results.
