Abstract
Ultra Wide Band (UWB) sensors are one of the greatest inventions to provide high security for power plants, reservoirs and other critical infrastructures by detecting unauthorized intrusion. The principle behind these is they use high fractional bandwidth and low frequency of operation. Compared to other Doppler radars these have very high resolution because of wide band width, and these have good propagation through many materials because of low frequency of operation. Types of UWB sensors are UWB Ground Penetrating Radar (GPR) to k ....etc

Tomographic imaging of electrically large objects in 2-D and 3-D environments using ultra-wideband (UWB) sensor arrays is described. Object cross-section electric properties is the most difficult part to model.Different industrial, medical, and security applications use microwave signals to penetrate and sense light opaque materials with reasonable spatial resolution.Increased level of spatial resolution and materialelectrical parameter measurement accuracy of Wideband signals, such as those produced with ultra-wideband (UWB) systems makes it ....etc

FCC on 2002 approves the use of unlicensed UWB for commercial purposes.
Although UWB technology is old, its application for
communication is relatively new, thanks to FCC.

Some mind-boggling applications including UWB Radar, Wireless USB, Wireless PAN, UWB

Endoscope,.(keep going)..I am sure, in near future UWB would overcome Blue-tooth and all

similar short range communication standards.

Here is one presentation I made to conduct a paper presentation contest in our college..

H-Shaped Dielectric Resonator Antenna for UWB application



INTRODUCTION
The extremely wide spectrum of 3.1 to 10.6 GHz with 15 bands of bandwidth greater than 500 MHz and power limit less than -41.3 dBm/MHz announced by FCC for Ultra wide band. The release of this Spectrum has rapidly increased the research in UWB technology for communications, radar imaging, and localization applications . Radio systems based on UWB technology offer opportunities for transmission of high data r ....etc
