Ultra-wideband sources and antennas
Ultra- Wideband Short-Pulse Electromagnetics 4 (IEEE Cat. No.98EX112), 2002Ultra-Wideband (UWB) sources and antennas are of interest for a variety of potential applications that range from transient radar systems to communications systems. In this paper, we discuss the research issues and progress being made in gas, oil and solid state switching, UWB sources, and antennas.

Ultra-Wideband and Its Capabilities
BT Technology Journal, 2003Ultra-wideband (UWB) can be seen as a disruptive technology for business and home wireless networking. Research into UWB systems can be dated back to the early 1960s, but until recently the main focus has been on radar-based, military secure radio and intrusion detection systems, as the short pulses of the signal results in very accurate timing ...

ULTRA: Wideband Ground Penetrating Radar
2006 European Radar Conference, 2006The frequency range employed in ground penetrating radar (GPR) systems is generally limited to 2 GHz because media loss increases dramatically at higher frequencies. Nevertheless, a series of applications exists in the Cultural Heritage field where the development of high frequency systems would significantly benefit, in terms of resolution, from an ...

Design studies of ultra-wideband microstrip antenna for ultra-wideband communication
2009 Loughborough Antennas & Propagation Conference, 2009This paper presents a circular printed monopole antenna for the Ultra-Wideband (UWB) applications. The antenna achieved over all bandwidth of 120% from operating frequency from 3.1 to 11.5 GHz for return loss

Chipless RFID tags require a significant amount of spectrum in order to encode their data. Hence, ultra wideband antennas seem like the obvious solution as the antenna of choice for the chipless RFID tag. The theory of operation and parametric study of circular disc monopole antennas printed on dielectric laminates is presented.

We report on the ultra-wideband transmission of 254 PCS-64QAM channels over 300 km of SSMF. We demonstrate a 107-Tb/s transmission throughput over a continuous 103 nm optical bandwidth using backward Raman pumping and SOA technology.

Ultra-wideband spectrum compliance
2020A political and technical challenge for developing an operational ultrawideband (UWB) surveillance radar is the ability to comply with the many international regulations on the radio frequency (RF) spectrum. It is clear that the worldwide regulations on the RF spectrum have made it more difficult to get licenses for radar operation.
