This paper discusses the principle of antenna which is used to determine the rotation of a radio station in the field of communication contrariety. The phase directionality function and amplitude directionality function of this antenna are developed. The relation of coupling between antennas and measured accuracy are also analyzed. It is helpful for people to design this type of antennas.
