TIME DOMAIN APERTURE ANTENNA STUDY Volume I (of 2)

摘要

The purpose was to develope direct time domain models suitable for analyzing and predicting the time domain behavior of reflector/TEM horn antenna systems. Three approaches were developed directly in the time domain suitable for predicting the impulsive radiation for reflector/feed antenna systems. Complete and detailed expressions and formulations are provided and all assumptions and approximations are completely described. Comparisons of the utility of the analytical solutions are provided by comparison with available experimental data for a number of TEM horns and reflector/horn configurations. The results of this research provide a unified and concerted approach for analyzing the radiation v.s. time behavior of aperture type antennas. It has been shown that the approaches developed are theoretically sound and selfconsistent within themselves as well as with C.W. antenna theory. A number of problem areas are identified and recommendations for further study made.
