【Abstract】 This paper presents a power dendity calculation model based on antenna near field gain,and describes the calculation method of reflector antenna near field region power density briefly.Taking the Gaussian distribution of circular aperture as an example,the power density of the reflector antenna in different regions is calculated,and the variation law of the power density in the near field region is analyzed.The power density in the near field region of the antenna axis is calculated at different taper levels and the influence of taper level on the near field region power density is studied.更多还原
