Comparison of induced ankle currents of the human-body equivalent antennas and anatomically human models exposed to nearby monopole antennas

In this paper, the induced ankle currents of the liquid-type human-body equivalent antennas are compared to those of their corresponding Japanese adult male and female models when exposed to monopole antennas placed at a distance of 3 m away. The purpose is to determining if they will be in good agreement like the case of plane wave exposure from which they were designed. The investigation of the monopole antennas exposure is important, because they have been used to provide experimental validation of the performance of the equivalent antennas. Our results indicate that good agreement in induced ankle current is obtained for the frequencies above 45 MHz. This may be explained by the fact that at the frequencies above 45 MHz, at 3 m distance away, the equivalent antennas appear to be at far fields of the monopole antennas, at which the fields becomes almost like those of the plane wave.
