PRINTED ANTENNA Russian patent published in 2010 - IPC H01Q9/00 

FIELD: radio engineering.

SUBSTANCE: printed antenna includes an antipodal slot line piece located on insulating substrate and signal strip line piece, similar signal and earth metal plates, piece of additional antipodal slot line the first and the second metal plates of which are identical to signal and earth metal plates respectively; at that, the first metal plate is located on one surface of insulating substrate in the area of aperture with signal metal plate, and the second metal plate is located on one surface of insulating substrate in the area of aperture with earth metal plate; at that, piece of additional antipodal slot line without overlapping does not have zero overlapping area; at that, in aperture area the first metal plate is galvanically connected with metal connection straps to earth metal plate, and the other metal plate is galvanically connected with metal connection straps to signal metal plate.

EFFECT: designing ultrabroadband printed antenna with low level of cross polarisation constituent part of electric field, side lobes.
