This paper presents a comparison study on the application of two electromagnetic inverse scattering algorithms, SEABED [1] and the synthetic aperture method, to experimental multi-static UWB (Ultra Wide-Band) radar data. A linear UWB antenna array with a wideband frequency (1.5-8 GHz) was used for the multi-static radar measurement in a realistic environment. The results clearly show the advant...

The ultra wide band antennas are required in applications where larger bandwidth for the transmitting signal is needed. They cover wide bandwidth in the range from 500 MHz to the frequencies above 8000 MHz. In this paper, a review of various techniques to realize ultra wide band microstrip antennas (MSA) is presented. They are realized by using different techniques like basic planar monopole an...

This solution is proved to be able to provide the system with the needed bandwidth. The self-configuration capabili...

this paper presents a low-cost compact planar microstrip-fed monopole antenna and its four-element array design for ultra-wideband (uwb) wireless communication and target detection applications, respectively, operating in the frequency span of 3 ghz to 11 ghz. a prototype was fabricated and then measured based on optimal parameters. the results of reflection coefficient (s11) and radiation patt...

This paper proposes a monopole antenna with photonic crystal structure as substrate for ultrawide band application with dual band notched characteristics.Improvements in all the main parameters of the antenna were obtained when using a PC.The measured results reveal that the presented dual band-notch monopole antenna offers a very wide bandwidth with two notched bands, covering 3.5/5.5-GHz WiMA...

A stacked type stair-case patch antenna with dielectric substrate (εr= 2.33) has been conceived and is theoretically demonstrated. Unlike conventional microstrip antenna it shows remarkable improvement in bandwidth (around 20%) as well as gain (around 10.5 dBi). The proposed structure is designed with two identical stair-case patches. Thorough investigations of the proposed antenna along with t...

A new application of utilizing ultra-wideband (UWB) technology to sense wind turbine blade deflections is introduced in this paper for wind energy cost reduction. The lower UWB band of 3.1-5.3 GHz is applied. On each blade, there will be one UWB blade deflection sensing system, which consists of two UWB antennas at the blade root and one UWB antenna at the blade tip. The detailed topology and c...

A V-shaped ultra-wideband antenna has been analyzed. Firstly, a rectangular planar monopole antenna has been studied and its base is tapered to obtain a better bandwidth. The feed-line is then offset for impedance matching. A bandwidth of around 14.3 GHz is obtained for this configuration. Then, a V-slot is cut in the patch and a parametric study of the width of the V-slot, the width of the pat...

With the beginning of the new information era, necessity of wideband wireless communica‐ tions technology is increasing rapidly due to the need to support more users and to provide information with higher data transmitting rates. Ultra-wideband (UWB) technology could be the most suitable technologies that promise to revolutionize high data rate transmission and enable the personal area networki...
