SMALL-SIZED DUALPOLARIZED WAVEGUIDE RADIATOR OF THE PHASE ANTENNA GRID WITH HIGH INSULATION BETWEEN THE CHANNELS Russian patent published in 2018 - IPC H01P5/08 

FIELD: physics.

SUBSTANCE: invention refers to microwave technology, in particular, to two-polarization emitters, which are used in the on-board X-band dualpolarized scanning phased array antennas (FAS), as well as to the antennas of higher frequency ranges. Invention can be applied to a variety of radio-technical on-board and space systems with wide-angle electric scanning and with independent mutually orthogonal linear polarizations of the emitted (received) fields. Technical result is a significant reduction in the coupling coefficient between two mutually orthogonal channels up to the values within the range of -35…-65 dB (35…65 dB) and more, at the significant decrease in the transverse dimensions of the dualpolarized waveguide radiator up to about (0.59…0.62)λ₀, where λ₀ is the wavelength in free space, corresponding to the average frequency of the operating range.

EFFECT: significant increase in the insolation between two mutually orthogonal channels.
