Abstract
A reflector placed near a cellular telephone antenna is proposed to increase its radiation efficiency. In this study, a half wavelength dipole antenna at 900 MHz is treated as a cellular telephone model and a small plate reflector is placed between the antenna and a human head-sized phantom model. By using the finite-difference time-domain (FDTD) method, various kinds of materials, such as a dielectric material, a magnetic material, and a conductive material, are investigated for the reflector composition. Among them, a magnetic reflector having high μ and low μ (complex relative permeability: μ−jμ) is shown to be effective for increasing the radiation efficiency. © 2000 John Wiley & Sons, Inc.
