The Dyadic Green’s function about spherical-shell microwave windows is presented in this paper, with which the influence on radiation pattern caused by the hemispherical-shell microwave windows is analyzed. The results show that the effect on the radiation pattern is prominent with the enhanced side lobe and the narrowed main lobe when the beam waist of Gauss distribution field is large, while the effect weakens as the beam waist decreases, thus it is concluded that the hemispherical-shell microwave windows are fit for the Gauss feed with small beam waist but unfit for the feed with large beam waist.
