The ultra-wideband wireless personal area networks are expected to be most commonly employed in desktop environments. This paper presents a measurement campaign conducted on a typical office desk. A pair of omnidirectional UWB antennas and a vector network analyzer were used to measure the impulse responses over a frequency range spanning from 6 GHz to 8.5 GHz, in accordance with the UWB regulations...
The effects of a Klopfenstein tapered transmission line used to feed a typical planar monopole UWB antenna have been investigated in terms of impedance bandwidth, phase linearity and radiation properties. The analysis shows that the taper allows manipulation of the resonances occurring within the operating bandwidth. A Klopfenstein tapered feedline that matches the 50 Omega input impedance to 30 Omega...
