A number of wearable antennas suitable for implementation of UHF-RFID tags have been presented in the open scientific literature. All of them are characterized by a high sensitivity with respect to the coupling with the human body, both on the input matching and on the antenna efficiency. This work presents a numerical investigation performed over a couple of wearable, ungrounded, antennas configurations, which shows that their robustness can be related to the distribution of the electric and magnetic energy densities close to the antenna borders.

Abstract
A number of wearable antennas suitable for implementation of UHF-RFID tags have been presented in the open scientific literature. All of them are characterized by a high sensitivity with respect to the coupling with the human body, both on the input matching and on the antenna efficiency. This work presents a numerical investigation performed over a couple of wearable, ungrounded, antennas configurations, which shows that their robustness can be related to the distribution of the electric and magnetic energy densities close to the antenna borders.File in questo prodotto:
