Horn radiators with phase-correction decelerating (accelerating) lenses are widely used in antenna technology SHF and EHF ranges of electromagnetic waves. First of all, it refers to the possibility of transforming a spherical wave front (in the phase center of the horn) in the flat at the exit aperture of the horn, which allows to get a flat -phase opening the desired size and form a narrow radiation pattern. Horn radiators (antennas) supplemented decelerating (accelerating) lenses are called horn-lens. The paper considers horn-lens emitters with decelerating dielectric lenses in aperture-ring. Dielectric lens-ring is technological to manufacture and have a high repeatability of parameters in their mass production. The proposed design(pyramidal horn loaded circular aperture lens), despite the differences in the geometry of the opening horn and lens allows to optimize the constructive inclusion lens aperture in a pyramidal horn.
