FIELD: radio engineering. ^ SUBSTANCE: contactless marker is essentially characterized by microchip (16) and Y-shaped antenna, connected to microchip, which contains information required for object tracking, which may be read with the help of reader through exchange of electromagnetic waves of ultrahigh frequency. Antenna is an antenna of dipole type, which consists of three main wires, the first main wire (10), the second main wire (12), generating dipole with the first main wire, and the third main wire (14), which generates the second dipole with the first main wire. Angle between the firs and second main wires is equal to angle between the first and third main wires, and angle between the second main wire and the third main wire is in the range between 60 and 180. Each of the main wires comprises an auxiliary wire (24, 26 or 28) at its end, which is perpendicular to the main wire. ^ EFFECT: creation of contactless marker with an omnidirectional antenna. ^ 12 cl, 8 dwg |
