In this paper, a small ground-independent planar UWB antenna is proposed. It is designed to cover the UWB band of 3.1 - 10.6 GHz. The antenna is etched onto a piece of PCB. A notch is cut from the radiator to reduce the size of the planar antenna. The simulations and measurements show that its impedance characteristics are ground-plane independent. The performance of the antennas is tested in time...
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...
