Sažetak

In this paper, the radiation pattern of two experimental models of circular waveguide antenna arrays on spherical surface
is obtained experimentally and compared with theoretical patterns. We have omitted the phase delay of feed system signals because
we have only compared measured and theoretical results in order to verify theoretical results, without trying to improve the best
radiation characteristics of developed experimental models. Analysis was made with a developed moment method (MoM) program.
The spectral-domain approach to the analysis of the spherical antenna arrays is briefly presented in the paper. Measurements were
not performed in a well-defined anechoic environment.
