[Abstract]
For phased array antennas, the key to high beam-steering accuracy is the uniformity of channels amplitudes and phases. Based on the small & circular shape antenna, firstly, the chief factors are analysed. Then, the methods of reducing errors are introduced. This work has certain instructional significance to relevant engineering practice of small phased array antennas.
