The proposed band-pass filter contains a metallic screen and a slot with quarter-wave aperture resonators. For the purpose to reduce attenuation of electromagnetic radiation in the operating frequency band of the filter, the aperture resonators are installed at a distance from each other that is equal to the quarter of the electromagnetic wavelength and contain square areas of the surface with metallic coating. At the area of each resonator with metallic coating, a layer of dielectric material with a short-circuiting strip is provided. The area with metallic coating is connected to the opposite edge of the screen slot.
