✦ Synopsis

Microwave antenna imaging techniques are a practical are just beginning to emerge as an alternative microwave antenna and popular method for antenna diagnostic analysis. Phase retrieval measurements technique when it is impractical or impossible to methods, however, are just beginning to emerge as an alternative directly measure phase. Antenna imaging employing phaseless microwave antenna measurements technique when phase cannot be measurements requires that the phase information first be ''redirectly measured. This article focuses on recent advances in microtrieved.'' The reconstruction of the phase information from the wave antenna imaging, diagnostic techniques, and phase retrieval phaseless measurement data is known as the ''phase retrieval'' methods for bi-polar planar near-field antenna measurements. An problem.

overview of the bi-polar planar near-field technique is included. The This article focuses on recent advances in microwave antenna application of optimal sampling interpolation, holographic imaging imaging, diagnostic techniques, and phase retrieval methods for and diagnostics, and iterative Fourier phase retrieval for the bi-polar planar near-field modality is explored in detail. Experimental results bi-polar planar near-field antenna measurements. An overview of for a waveguide-fed slot array antenna are presented to illustrate the bi-polar planar near-field technique is included. The applicathese methods.
