• the advantage of this arrangement is that with parallel arranged (erected) bottles, the respective antennas are aligned with a uniform orientation and thus can preferably be read with a uniform, parallel orientation of the antenna of the reader.
• On a conveyor line transverse to the bottle axis so that a defined selective readout of each located in the main beam direction transponder is possible. The preference for a more distant transponder (incorrect reading) due to different orientations is thus excluded.
• the container 1 and / or the conveying path comprises a means which prevents the container from rotating about its own axis.
• the container and / or the conveying path may comprise a means which ensures a minimum distance of the lateral surfaces of adjacent bottles.
• FIG. 8 shows the RFID marking of a cylindrical vessel 1 whose cylindrical main section 12 is shorter in the axial direction than the length of the dipole antenna 122 which is optimal for the transponder 2 in the desired frequency range.
• the dipole antenna 122 in this case becomes an open coil around the cylindrical main section 12 of the vessel 1 is arranged.
• the coil axis is arranged according to the invention parallel to the cylinder axis.
• the extension of the antenna in the direction of the cylinder axis -in other words, the pitch of the open coil-is selected to be as large as possible. In any case, the pitch of the coil is greater than the width of the track of the antenna 122.
• FIG. 8 a shows a transponder 2 with transponder chip 21, dipole antenna 122 and connecting wires 23 on a flexible substrate 3, which is suitable for RFID marking of the vessel 1 just described.
• FIG. 8c shows the finished, labeled vessel 1 with transponder 2 and substrate 3.
