FIELD: antenna equipment.

SUBSTANCE: invention can be used for receiving and determining the direction of arrival of linear polarization radio signals as part of a digital antenna array of two frequency ranges. Substance of the invention consists in the fact that the curtain of the waveguide receiving antenna array of linear polarization of two frequency ranges with bands of 40% and 22% consists of a conducting base, on which there are 4 waveguide emitters of linear polarization, wherein base of AA is from 3.6λ₀ to 3.8λ₀, where λ₀ is the wavelength in free space, corresponding to the average frequency of the operating range; length of the distance from the centre of the first radiator to the edge of the base of the AA is from 1.07λ₀ to 1.09λ₀; length of distance from the centre of the fourth radiator to the edge of the base of the AA is also from 1.07λ₀ to 1.09λ₀; length of the distance from the upper edge of the fourth radiator to the edge of the base is from 1.21λ₀ to 1.23λ₀; length of the distance from the upper edge of the first radiator to the edge of the base of the AA is also 1.21λ₀ to 1.23λ₀; length of the distance from the side edge of the fourth radiator to the edge of the base of the AA is from 0.46λ₀ to 0.48λ₀; length of the distance from the side edge of the first radiator to the edge of the base of the AA is also from 0.46λ₀ to 0.48λ₀; AA base length is 29.4λ₀ to 29.6λ₀, AA base thickness is 0.04λ₀ to 0.06λ₀; distance between phase centres A₁-B₁ of radiators is not less than 1.94λ₀; distance between phase centres A₁-A₂ of radiators is not less than 6.23λ₀; distance between phase centres A₁-A₃ of radiators is not less than 17.1λ₀; distance between phase centres A₁-A₄ of radiators is not less than 27.2.λ₀; distance between phase centres A₄-B₄ of radiators is not less than 1.94λ₀; distance between phase centres A₄-B₃ of radiators is not less than 15.3.λ₀; distance between phase centres A₃-B₂ of radiators is not less than 2.3λ₀; distance between phase centres B₂-A₂ of radiators is not less than 3.2λ₀; and provides angle selectivity, where λ₀ is the average wavelength of the working range in vacuum.

EFFECT: providing the possibility of increasing the operating frequency band of the waveguide receiving antenna array curtain of linear polarization.
