Abstract

The FDTD (finite-difference time-domain) technique is used to investigate the radiation patterns, polarization characteristics, and correlation coefficient for a diversity antenna employing two PIFA (planar inverted-F antenna) elements located on a rectangular conducting box. A second-order absorbing boundary condition is used to truncate the computational volume at a distance of 12 cells away from the antenna/handset configuration. A wire subcell method is employed to properly incorporate the effects of the finite size of the feeding wire.<>
