Description
Summary:In this paper the interaction of the planar inverted-F antenna array, mounted on a mobile handset, with a human hand-head phantom is investigatedin the 1.9 GHz band. The hybrid approach involving the particle swarm optimization (PSO) and Nelder-Mead (NM) algorithm is considered to optimize the complex excitations of the adaptive array elements in a mutual coupling environment for different beamforming synthesis. Firstly, the effect of the human hand-head on the handset radiation characteristics is studied. Then, the spatial peak specific absorption rate (SAR) values of 4-element antenna arrays for mobile handsets in the vicinity of a human hand-head are evaluated numerically for different scenarios. The antenna is analyzed completely using finite difference time domain (FDTD)while the interaction is performed using the CST Microwave Studio software.
