LENS ANTENNA Russian patent published in 2017 - IPC H01Q15/08 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to novel lens antennas for use in various applications of millimeter-wave radio communication systems, such as point-to-point microwave communication systems and transport networks of mobile cellular systems, radars, satellite and inter-satellite communication systems, local and personal communication systems and others. The antenna contains a lens and an antenna element. In this case, the lens consists of a collimating part and a part of the elongation made for one of the dielectric material. On the lengthening part, a flat platform is made, which intersects the axis of the collimating part, and the antenna element is rigidly fixed on the site. The antenna element is made in the form of a hollow waveguide, the radiating opening of which is facing the lens, and includes a transitional region of variable cross-section between its input and radiating openings. Moreover, the antenna element comprises a dielectric insert having the same cross-sectional shape as the radiating opening of the hollow waveguide, and made in one with a dielectric lens of one material.

EFFECT: increasing the gain of a broadband aperture antenna.
