HYBRID MIRROR ANTENNA Russian patent published in 2021 - IPC H01Q19/00 

FIELD: antenna technology.

SUBSTANCE: invention relates to antenna technology, in particular to hybrid antennas, and can be used in radar, communications and electronic warfare systems. The effect is achieved by the fact that the hybrid reflector antenna includes a linear array of horns with input waveguides of rectangular section and a mirror in the form of a parabolic cylinder, an additional horn of rectangular section and phase-correcting elements, while the horns of the array are E-sectorial, the walls of the E-sectorial horns are expanded in the plane parallel to the focal axis of the parabolic cylinder, their output dimensions exceed the wavelength, the dimensions of the input and output sections of the additional horn in this plane are equal to the length of the array of the E-sectorial horns, and the walls of the additional horn are expanded in the orthogonal plane, and the phase-correcting elements are installed between the outputs of the E-sectorial horns and the input of the additional horn.

EFFECT: simplification of the design while maintaining high values ​​of the gain and surface utilization.
