Abstract :
FDTD modeling of two handset-mounted antennas in the proximity of the user was performed to investigate the effects of some aspects of the communications environment on antenna performance. We have shown that: (i) the antenna mean effective gain (MEG) is strongly influenced by the type of the environment; (ii) much less power is absorbed in the user´s head when the polarization diversity antenna is used instead of the monopole antenna; and (iii) antenna performance is underestimated if ground reflections are not taken into account.
