Abstract
To provide an antenna for dipole-type IC tag, which can conform to various IC chip specifications and communication frequencies in a wide area without causing an increase in the size of antenna, while advantageously suppressing a decrease in a communication distance caused by a defect part in an antenna pattern, in an antenna for dipole-type IC tag, an antenna radiation part is configured by extending an antenna wire in a radiation part extending direction, while repeatedly forming a pair of branch paths that branches in a direction intersecting with the radiation part extending direction, and a connection path which connects the pair of branch paths. The connection path is configured to extend in the radiation part extending direction from a junction of a pair of branch paths to a branch point of a next pair of branch paths.
