The problem of evaluation and studies of the noise immunity of the microwave antenna by the method of mathematical modeling is discussed. A mathematical model allows to evaluate the noise immunity of the antenna taking account into its radiation pattern, the influence of the shape and width of the main lobe and structure of the side lobes by submitting them on a separate angular intervals of a combination of known features corresponding to the main and side lobes. The resulting estimate of the noise immunity of the microwave antenna taking account the sensitivity of the receiver radio system, in which it is used. The results show that with an acceptable accuracy for practice, the proposed mathematical model allows to estimate the probability of penetration of the electromagnetic interference through the antenna.
