UWB: Can 40 Years of Impulse Work Help Communications?

Above: An antenna being measured and modeled for UWB communications purposes. Above: The transient response of the antenna to a short pulse, which is the basic signal used for UWB.

E&M researchers have been investigating ultra wideband (UWB) technology in an attempt to move the impulse work of the last 40 years into a potential measurement and communications medium. Current emphasis is the measurement and modeling of antennas (VTAG) and propagation channels effects (TDL). This information is background for the communication system model being developed by communications researchers (see article page 27). UWB is also being investigated in relation to non-communications applications.
