“…5, where the position of the transmit and of the receive antenna (9 different positions have been considered) are also shown. This scenario has been implemented in a raytracing tool, which permits to calculate the different multipath components caused by reflections from the objects [10]. The receiving antenna has always been positioned in line of sight, at the same height (2 m).…”

In this paper a complete analysis of the non-idealities in Ultra Wideband (UWB) systems is presented, from both a component point of view and a system point of view. The behaviour of a realistic UWB transmission scenario is investigated with both simulations and measurements of fabricated components. I. INTRODUCTIONUltra Wideband (UWB) is a wireless technology, whose usage of a very huge bandwidth permits to achieve many advantages for different applications: for example, high data rate for communication applications, high resolution for Radar and localization purposes … [1].Since the allocation of a frequency band for UWB purposes in US [2] and in Europe [3], many contributions of UWB components have been presented in literature: antennas, filters, RF-front end… [1]. Moreover, also many system aspects (such as bit-error-rate (BER), signal-to-noise ratio (SNR), …) of the UWB transmission have been assessed.One crucial aspect in UWB systems is the non-idealities of the system itself. The non-idealities provoke a worsening of the transmission and hence a changing of the system performance w.r.t. the ideally expected one. Hence, the investigation of the impact of the non-idealities on the system performance is an important task. Moreover, having a quantification of these non-idealities permits to introduce correction strategies.The aim of this paper is to investigate the non-idealities in the RF-front end and to quantify their impact on the signal transmission. The paper concentrates on a communication point of view. A similar, dedicated analysis could be extended also to Radar scenarios.The paper is organized as follows: in the next section the UWB transmission is presented, deriving the UWB radio link equation for impulse radio transmissions and highlighting the non-idealities of each component of the UWB transmission system. In Section III the non-idealities of the presented UWB scenario are investigated. Finally, in the last section the impact of these non-idealities on a realistic UWB communication scenario is assessed, calculating the worsening of the BER when real component are consider w.r.t. the case of an ideal system.

“…In this case the results of conventional ray tracing follow the measurement very well. Furthermore in [14] the hybrid method has been verified in a realistic, complex scenario, showing that if the position of the small objects is in the proximity of the transmitter/receiver, the hybrid method delivers more accurate results than the conventional ray tracing.…”

-In this paper an approach for object recognition by the backscattered UWB signals is presented. This approach is a part of an UWB imaging and localization concept for emergency scenarios, where fire and smoke prevent using optical systems. The proposed recognition method is particulary useful to asses the intactness of the building construction elements. As such elements are usually composed of different materials, often including a metallic core, the recognition of inner structures is of great interest. For effective optimization and application of the recognition approach reference data sets are necessary. These reference data sets are obtained by a hybrid ray tracing/FDTD method, which allows for the simulation of small complex and inhomogenous objects in realsitc indoor scenarios.

“…Recently, to fabricate transparent antennas, transparent indium tin oxide (ITO) and fluorine doped tin oxide (FTO) conductive films are utilized [8,9]. These films allow transmission of electric currents while provide good optical transparency [10]. However, the reported antennas using ITO and FTO are not studied for ISM band as well as for transparent substrates.…”
