A general theory on the graphical representation of antennaradiation fields
Abstract
A general theory for graphical representation of antenna radiated fields is developed. The application of the method to the special case of a transverse electromagneticmodeexcited biconical antenna is investigated in detail. Electric field lines in the rtheta plane of a spherical coordinate system are presented in a manner such that the same electric flux is always carried between two neighboring field lines. Thus, their mutual distance is a criterion for the strength of the local electric field. The differential equations which govern the displacement of a field point are derived and solved. The timedependent evolution of a fieldline pattern is examined in detail. The new theory for graphical field representation permits, in an elegant manner, the analysis of the transmission and receiving mechanism of arbitrary antenna configurations. Thus, it is suggested that an iterative graphical synthesis procedure could, in the future, be applied to the computeraided design modeling of antenna shapes.
