Document Type and Number:
WIPO Patent Application WO/2012/063913
Kind Code:
A1
Abstract:
The present invention relates to a folded dipole antenna comprising, in a magnetic body having a hexagonal Z-type ferrite and/or a hexagonal Y-type ferrite as a main component, a radiating element and a reflection element that have a folded dipole structure, and to an RF tag in which an IC chip is connected to the folded dipole antenna. This RF tag, as compared to conventional RF tags, is smaller, is less likely to be impacted by the surrounding environment, and operates using a UHF band or a nearby frequency band.
