REFLECTOR ANTENNA INCLUDING DUAL-BAND AUXILIARY REFLECTOR HOLDER Russian patent published in 2017 - IPC H01Q13/20 

FIELD: antenna.

SUBSTANCE: invention relates to antenna technology. Antenna includes: dual-band waveguide feed (210; 810; 910), made with possibility to receive input signal on first transmission mode and having means for upper frequency band transmission mode conversion from first transmission mode into mixed transmission mode, including first transmission mode and second transmission mode; reflector; secondary reflector (230, 830), made with possibility of beam direction, emitted from waveguide feed aperture (210A), reflector; and holder of auxiliary reflector (240; 840; 940), containing first coupling part (240a; 840a; 940a) for coupling with waveguide feed, second coupling part (240c; 840c, 840c) for coupling with auxiliary reflector and holding part (240b; 840b; 940b), connecting first coupling part with second coupling part and made with possibility of setting space between waveguide feed aperture and auxiliary reflector. At that, holding part has thickness smaller than or equal to, substantially, λ/2, where λ is beam specific wavelength in holding part.

EFFECT: technical result consists in ensuring auxiliary reflector holder structural rigidity preservation at relatively low reverse losses in entire frequency band.
