| Abstract: | In this paper perturbational expansion of wave equation is used to analyse the Gaussian beam radiation efficiency and the near field distribution of aperture antenna. The analysis is also suitable at large angles from boresight because the Gaussian beam used here is corrected to satisfy wave equation. An approach of minimum deviation of aperture field is used to calculate the Gaussian beam radiation efficiency, and calculation results is compared with that of Wydle's[1]. |
