The polarization characteristics analysis of the electromagnetic field of the aperture random antenna is performed by the statistical simulation method. This random aperture antenna consists of three rectangular apertures and simulates a window in an office. The computer version of the Monte Carlo method used to simulate the stochastic error as part of the signals exciting aperture random an-tenna. The Emitter Huygens is a basic element of the aperture random antenna. Each of the three apertures in the composition of the aperture random antenna includes four correlation cluster. Stochastic errors within one cluster are considered the same and they are in-dependent from each other for the different clusters. The article presents the histogram of the angular characteristics φЕ;Н; θЕ;Н, which determine the polarization properties of the field vectors of the aperture random antenna at frequencies of 200 MHz and 6 GHz. The frequency of 200 MHz corresponds to the conditions of the Fresnel zone, the frequency of 6 GHz - the conditions of the Fraunhofer zone. The proposed method of modeling the polarization properties of the field of the aperture random antenna is a clear and universal. The practical application of this method – is designing systems of information protection against leakage to the outside environment through the aperture random antenna.
