Folded dipole antenna and RF tag using the folded dipole antenna

摘要

The present invention relates to a folded dipole antenna comprising a magnetic material comprising a hexagonal Z-type ferrite and/or a hexagonal Y-type ferrite as a main component in which a radiation element and a reflection element each having a folded dipole structure are disposed, and an RF tag comprising the folded dipole antenna and an IC chip connected to the folded dipole antenna. The RF tag according to the present invention has a smaller size than that of the conventional RF tags and is not susceptible to adverse influence from ambient environments, and can be operated at an UHF band or surrounding frequency bands thereof.
