Abstract
This paper characterizes the ultra-wideband (UWB) antennas in proximity of human head using an FDTD method. In the study, a numerical head model of frequency dependent dielectric constant and conductivity is used. The performance of the antennas printed on PCB is investigated in terms of the impedance matching, radiation patterns, and gain. The information derived from this study is conductive to the design of the UWB antennas applied around human heads
