BAND BEAMED ANTENNA Russian patent published in 2017 - IPC H01Q13/02 

FIELD: radio engineering, communication.

SUBSTANCE: introduced the transition cup from coaxial to coplanar line 7, the supply coaxial cable 8 grounding cup, the coplanar line 5 with the central conductor width 0.38 mm, the gap 0.2 mm, the coplanar resistance transformer 6 with the length 0.11λ_max with gradually changing the width of the central conductor from 0.38 to 0.19 mm and the gaps from 0.2 to 0.24 mm, the diameter of the metal zigzaging sheet 1 is 0.3λ_max and the slit 4 of the metal zigzaging sheet is made symmetrical to the antenna center with the common axis of symmetry, the cutouts in the shape of two segments with the height 0.024λ_max of the circle with the diameter 0.27λ_max, two sectors with the circle angle 28° with diameter 0.23λ_max, two rectangles with the height 0.06λ_max and the width of 0.016λ_max, supported to the axis of symmetry by the smaller side, the diameter reflector-screen is equal to the diameter of the dielectric substrate and it is 0.38λ_max. The proposed technical solution allows to increase the amplification factor in the frequency range with the overlap factor 2.2 not less than by 1 dB and with the overlap factor 2.8 not less than by 0.4 dB.

EFFECT: increase of the antenna amplification factor, while keeping the operating frequency range of the band beamed antenna.
