| 摘要 |
The invention relates to a radio-frequency identification label for the wireless remote transmission of a code, which label, on the outside, is of substantially cylindrical form (a so-called bolus) and can be permanently arranged in one of the stomachs of a ruminant, with the particular feature that the axial direction of the bolus which is most sensitive to detection is held in a position, with respect to the interrogating field, which provides a maximum detection distance.
