Ultra-Wideband Terahertz Absorption Using Dielectric Circular Truncated Cones
IEEE Photonics Journal, 2019 We numerically demonstrate an ultra-wideband terahertz absorber using dielectric circular truncated cones on a non-structured graphene layer supported by a dielectric spacer on a metal reflector in the bottom.

An Investigation of Bluetooth Mergence with Ultra Wideband [PDF]
2008 Third International Conference on Broadband Communications, Information Technology & Biomedical Applications, 2008 This paper presents an investigation into some merging options between an upper-layer Bluetooth (BT) protocol stack with a lower-layer ECMA-368/9 ultra wideband (UWB) radio connection. A Bluetooth over ultra wideband (BToUWB) system is modeled by channeling an existing compliant Bluetooth connection's data over a software implemented UWB medium access ...

On Rapid Re-Design of UWB Antennas with Respect to Substrate Permittivity
Metrology and Measurement Systems, 2016 Re-design of a given antenna structure for various substrates is a practically important issue yet non trivial, particularly for wideband and ultra-wideband antennas. In this work, a technique for expedited redesign of ultra-wideband antennas for various

An ultra-wideband origami microwave absorber
Scientific Reports, 2022 Microwave absorbers have been used to mitigate signal interference, and to shield electromagnetic systems. Two different types of absorbers have been presented: (a) low-cost narrowband absorbers that are simple to manufacture, and (b) expensive wideband ...

, 2015 The focus of UWB antenna research activity has matured in recent years and currently mainly concentrates on applications such as biomedicine and security. Early UWB antenna designs were driven by the FCC allocation of spectrum in 2002 and focussed on obtaining wide impedance bandwidths with reasonable group delay characteristics.
