Effects of an electrically large rotation ellipsoid radome on the radiation characteristics of two kinds of antennas
The effects of the electrically large rotation ellipsoid radome on the radiation characteristics of two kinds of wire antennas are analyzed by an improved hybrid method, which combines the method of moments (MOM) and physical optics (PO). Based on a group of associated integral equations, the mutual interactions among the antenna, the inner and outer surfaces of the radome are all considered. In the analysis, the antenna surface and the sharp tip part on the radome surface are modeled accurately by using MOM, while the smooth parts on the radome surfaces approximated by using PO method. Numerical results indicate that the radome parameters can affect the antenna radiation characteristics seriously.
