Sažetak
The influence of model errors on radiation pattern of a hemispherical aperture antennas arrays is studied in the paper. Analysis was made with a developed moment method program that analyzes a particular influence of an azimuth and elevation position and local angle errors of the second waveguide as well as model dimension errors on radiation pattern. The spectral-domain approach to the analysis of the spherical antenna arrays is presented in the paper. Theoretical free-space normalized radiation patterns of two waveguide antennas on the spherical surface with more details are analyzed in this paper. Assumed values of the theoretical model errors are in the range of expected real model errors.
