An Interaction Study Between PIFAs Handset Antenna and a Human Hand-Head in Personal Communications
Abstract|In this paper, the interaction of a planar inverted-F antennas array, mounted on a mobile handset, with a human hand-head phantom is investigated in 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 di®erent ... إقراء المزيد
