"Narrowband"

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, …

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 …
