Recent Trends in Printed Ultra-Wideband (UWB) Antennas

After the Federal Communication Commission (FCC)’s authorization of frequency band of 3.1 to 10.6 GHz for unlicensed radio applications, ultra-wideband (UWB) technology be‐ come the most promising candidate for a wide range of applications that will provide signif‐ icant benefits for public safety, business and consumers, and attracted a lot attention both in industry and academia. The antennas...

Ultra - Wideband ( UWB ) Wireless System

Ultra wide bandwidth (UWB) signals are commonly defined as signals that have a large relative bandwidth (bandwidth divided by the carrier frequency) or a large absolute bandwidth .On the other hand, generating, receiving, and processing UWB signals poses significant challenges that require new research in signal generation, transmission, propagation, processing, and system engineering. In the p...

Introduction to Ultra-wideband Antennas

In addition, a UWB antenna is preferentially nondispersive, having a fixed phase center. If waveform dispersion occurs in a predictable fashion it may be possible to compensate for it, but in general it is desirable to radiate similar waveforms in all directions. A logperiodic antenna is an example of a dispersive antenna. Larger scale components radiate low frequency components while smaller s...

Ultra-Wideband Printed Antennas Design

On February 14, 2002, the Federal Communications Commission (FCC) of the United States adopted the First Report and Order that permitted the commercial operation of ultra wideband (UWB) technology (FCC, 2002). The FCC allocated a bandwidth of 7.5GHz, i.e. from 3.1GHz to 10.6GHz, to unlicensed use for UWB applications. Ultra Wideband is defined as any communication technology that occupies great...

Influence of the Antennas on the Ultra-Wideband Transmission

Spectrum is presently one of the most valuable goods worldwide as the demand is permanently increasing and it can be traded only locally. Since the United States Federal Communications Commission (FCC) has opened the spectrum from 3.1GHz to 10.6GHz, that is, a bandwidth of 7.5GHz, for unlicensed use with up to −41.25dBm/MHz EIRP, numerous applications in communications and sensor areas are show...
