Magnetic Substrate Folded Dipole Antenna for UHF RFID Metal Tag
By
Progress In Electromagnetics Research Letters, Vol. 47, 25-30, 2014
Abstract
In this paper, magnetic material was applied in the design of a UHF-RFID metal tag to increase the reading distance. The influence of the electromagnetic properties, especially the electromagnetic loss, of magnetic substrate on the gain of the tag antenna is discussed by analyzing the reflection and the surface current distribution. As to folded antenna, the loss of energy caused by the magnetic substrate tends to occur in the folding edge of the antenna. Both simulations and experiments indicate that electromagnetic loss markedly reduces the gain rapidly when both the dielectric loss tangent (tanδ) and the magnetic loss tangent (tanδm) are between 0 and 0.3. The reading distance drops from 3 m to 1.5 m when the tanδm of the magnetic composite substrate increases from 0.009 to 0.023. And tanδm should be less than 0.1 for the antenna working excellently. The conclusion offers meaningful guidance for future studies of magnetic substrate folded metal tag.
