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, …
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 …
Synthesis of ultrawideband (UWB) antennas by means of a particle swarm optimizer (PSO)-driven spline-based shaping approach is described. In order to devise a reliable and effective solution, such a topic is analyzed according to different …
In this paper, an innovative spline-based approach for the UWB antennas synthesis has been proposed. The flexibility and accuracy of the method allows a reliable matching of UWB requirements. A representative design example described through the …
This letter presents the design of a planar antenna for ultrawideband (UWB) applications with a bandwidth of 5.5 GHz over 3.7 to 9.2 GHz and return loss values lower than -10 dB. The antenna geometry is described in terms of a spline-based …
