Wave excitation on human body by a short dipole

In this paper, the propagation mechanism of a short dipole antenna on a flat phantom made of fat and muscle tissue properties is investigated. Both vertical and horizontal dipoles are considered in this study. It is shown that, the performance of a parallel dipole near to the surface of the body phantom is completely different from the free space. The parallel dipole on the body excites stronger fields along the antenna rather than any other directions on the surface. The propagation modes for both vertical and horizontal antennas are discussed by the use of Norton equations. Also, a pair of antennas is mounted on the flat and real body phantom and the transmission channel gains are evaluated for different antenna combinations and arrangements.
