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

FIELD: radio engineering.

SUBSTANCE: in printed antenna which includes lower dielectric layer (1), upper dielectric layer (2), lower metal layer (3) located on lower surface of lower dielectric layer (1), middle metal layer (4) located between upper dielectric layer (2) and lower dielectric layer (1) and upper metal layer (5) located on upper surface of upper dielectric layer (2) and excitation elements (8), in middle metal layer (4) of printed antenna there made is crossed slot (6) consisting of two crossing slots, and four metal connection straps (7) connecting middle metal layer (4) and lower metal layer (3) are introduced.

EFFECT: decreasing dimensions of printed antenna, providing reception and transmission of waves with circular polarisation at maintaining working frequency band.
