UWB is a wireless technology that transmits binary data-the 0s and 1s that are the digital building blocks of modern information systems. It uses low-energy and extremely short duration (in the order of pico seconds) impulses or bursts of RF (radio frequency) energy over a wide spectrum of frequencies, to transmit data over short to medium distances, say about 15-100 m. It doesn't use carrier wave to transmit data.

UWB is fundamentally different from existing radio frequency technology. For radios today, picture a guy watering hi ....etc

ULTRA- FAST ULTRA - HIGH INTENSE LASER




ABSTRACT

The year 2008 will probably known as the year of ultra mobile PCs with a slew of Ultra Mobile PCs being released by different companies. Ultra mobile PC promises to support wired or wireless network to which is a major plus as gives a number of options for net connection along with mobility. On the specification side the device sports s 7 inch LCD screen with a resolution is a ....etc

Abstract
Sampling is the bottleneck for ultra-wideband (UWB) communication. Our major contribution is to exploit the channel itself as part of compressed sensing, through waveformbased pre-coding at the transmitter. We also have demonstrated a UWB system baseband bandwidth (5 GHz) that would, if with the conventional sampling technology, take decades for the industry to reach. The concept has been demonstrated, through simulation ....etc

Abstract—

Fractals have very unique properties, therefore
in recent years, antenna designers use fractal geometry in
multi-band and broad-band antennas designing.
In this paper, I have achieved to a 40GHz super
wideband antenna with applying a fractal geometry to a
wire square loop antenna and choosing appropriate size
and location for feeding. Mode ....etc

Abstract:
A patch antenna is presented which has been designed to radiate frequencies in the range 4–9.5 GHz into human breast tissue. The antenna is shown by means of previously unpublished simulation and practical measurements to possess a wide input bandwidth, radiation patterns that remain largely consistent over the band of interest and a good front-to-back ratio. Consideration is also given to the antenna’s ability to radiate a pulse, and in this respect it is also found to be suitable for the proposed application.
