Abstract: This paper presents simulation results that evaluate the effect of loop-like jewellery items (rings and bangles) worn on human fingers and wrist on SAR in the human head and the hand. The jewellery items were modelled as conducting objects with the typical commercial sizes available. Rings were placed on different fingers in a computer model for comparison purposes. The amount of energy absorbed in the head/hand and the effect brought about by the jewellery are shown to vary for different antennas. In this study, a monopole and a PIFA antenna have been employed. The results obtained indicated that: (i) by using a monopole antenna, the peak and average 1g SAR in the head are slightly decreased by the introduction of the ring and bangle, (ii) by using a PIFA, the peak and average 1g SAR in the head are increase by more than 12% and 11% respectively by the metallic rings.
