Abstract :
Measurement of radio frequency (RF) radiation performance has been investigated for mobile terminals including the influence of the human body. Recent studies have shown that the user´s hand has a greater influence on antenna radiation performance than the head. Therefore, a hand phantom needs to be included in the evaluation of the RF performance of a mobile terminal. We developed a lightweight tissue-equivalent phantom, ultra light carbon phantom (ULCP®), consisting of a head and upper body, for application to three-dimensional (3-D) RF radiation measurement. In this paper, the development and evaluations of the hand of the ULCP is presented. The RF performances of a dipole antenna and a mobile terminal with the ULCP hand are evaluated in comparison with a number of human test subjects. Finally, it is confirmed that the ULCP hand is useful for mobile terminal tests including the influence of the human hand.
