DUAL BAND DIPOLE PRINTED ANTENNA Russian patent published in 2023 - IPC H01Q3/38 H01Q1/38 H01Q5/48 

FIELD: antenna technology.

SUBSTANCE: invention is used for the design, modelling and manufacture of dual-band antennas. The technical result is separate control of the central frequencies of the antenna matching bands, as well as a reduction in the overall dimensions of the antenna. The technical result is achieved by the fact that the arms of the dipoles are made on different sides of a thin dielectric substrate with a low value of the dielectric loss tangent, the dipoles are connected to each other by a short section of a transmission line with a characteristic impedance of 100 Ohms, and are connected to a supply transmission line with a characteristic impedance of 50 Ohms by a section of the transmission line with a characteristic impedance of 70.7 Ohms, the antenna is configured to be powered by connecting the grounded pole of the generator to one side of the supply transmission line with a characteristic impedance of 50 Ohms, and the signal pole of the generator to the other side of the supply transmission line with a characteristic impedance of 50 Ohms.

EFFECT: separate control of the central frequencies of the antenna matching bands, as well as a reduction in the overall dimensions of the antenna.
