MOBILE PHONE ANTENNA Russian patent published in 2008 - IPC H01Q1/38 

FIELD: physics; electricity.

SUBSTANCE: invented antenna consists of packet like connected electroconductive upper 1, lower 2 and dielectric 3 concave plates with edges on the perimeter of an arched shape, arranged one on top of the other on a carrier dielectric substrate 4. The electrocunductive plates 1 and 2 are separated from each other by dielectric plate 3. In electroconductive plate 2 and dielectric plate 3 there is common through hole 5. The antenna has lateral sides 6 and 7, vertical axis 8, upper 9 and lower 10 parts. Coaxial cable 11 is used for external connection, which has an external 12 and internal 13 conductor and is put through the through hole 5 in the lower part 10 of the antenna. The outer conductor 12 of coaxial cable 11 is connected to the lower part 10 of electroconductive plate 2 through a cylindrical tapered pipe 14. The inner conductor 13 of the coaxial cable 11 is connected to the lower part 10 of the electroconductive plate 1 through a cone shaped tapered pipe 15.

EFFECT: protection from radio-frequency radiation and longer range with minimum signal distortion.
