PHASE THEORY OF ANTENNA BEAM
天线波束相位理论

The traditional requirements for the antenna are reviewed. Under such background and on the basis of previous work, the subjects concerning the phase of antenna beam and the current distribution of antenna aperture, such as the phase reference point, the trans-formation relationship of the far field patterns corresponding to different phase reference points of an antenna, the null level and phase difference between the adjacent beams, and the resolution of current distribution of the linear array are systematized and discussed. The general condition of the beam in phase and the condition of the symmetric beam of a continuous linear array are given and proved theoretically. Some theorems are proposed, and the whole is termed the phase theory of antenna beam.
