In this paper, a time domain analysis for the synthesis of antennas suitable for Ultra-Wideband (UWB) communications is presented. Towards this end, a set of time domain requirements that guarantee good impedance matching, distortionless properties, …
In this paper, an approach for the synthesis of antenna systems suitable for UWB communication applications has been presented. The final antenna geometry is obtained by means of a PSO aimed at fitting a set of time domain requirements. Such …
The advantages of multiple-input multiple-output (MIMO) technology in ultrawideband (UWB) communication systems are investigated evaluating the channel capacity from measurements taken in indoor environments. The results suggest that in practical …
In this paper, an innovative approach for the synthesis of antennas fitting the requirements of an UWB communication system has been presented. Such an approach allows one to design UWB antennas with distortionless propagation properties as well as …
In this paper, an experimental evaluation of the performances of a MIMO-UWB system has been described. The results obtained show that only at short distances MIMO-UWB systems exploit a significant multiplexing gain. This is mainly due to the SNR of …
A spline-shaped antenna for ultra-wideband communications that operates in the Electronic Communications Committee (ECC) released band from 6 up to 8.5 GHz is described. Selected simulated and measured data are reported to assess the achieved …
