Animal ear tag

The invention relates to an animal ear tag which is intended to be able to be anchored on an animal's ear by means of a dome (25) and which has a housing (2, 23, 30, 33) enclosing an electronics assembly (1) and a battery (6, 21), and a panel surface (12, 22, 31, 34) on which identification data relating to the animal are intended to be directly visible in clearly legible characters, wherein the panel surface (12, 22, 31, 34) is located below the housing (2, 23, 30, 33) when the ear tag is placed on the animal. The centre of gravity of the housing (2, 23, 30, 33) and of the parts enclosed by the latter lies inside an area (15) protruding downwards from the spike axis (8), which area (15) is not higher than 2 cm and, in the horizontal lying normal to the spike axis (8), is not wider than 1 cm. Animal ear tags with transmitters have the problem of providing a strong transmission signal, this issue is solved by having the antenna (7) is arranged as far as possible from the battery (6) and additionally arranged at the highest possible point of the animal ear tag such that the transmission and reception quality are improved compared to other designs in terms of the energy which is consumed.
