Abstract
A good approach when designing antennas for
mobile terminals is to optimize them for operation in the vicinity
of the user body. The presence of a lossy human tissue in the
antenna’s near field has an adverse effect on the radiator’s
performance. The focus of this paper is on studying the change
in the antenna performance due to the change in the dielectric
properties of the human hand holding the mobile terminal. The
investigation is conducted by using an antenna array consisting
of two identical and symmetrical PIFA antennas covering the
frequency band from 5.8 GHz to 7.7 GHz. Several different
values of the complex permittivity are assigned to a human hand
phantom in the numerical simulations and it is found that the
variation of the complex relative permittivity within a large range
of values does not change largely the S-parameters and radiation
efficiency of the antenna.
