I n this paper, two novel ultra wideband (UWB) minimized antennas based on the composite right/left-handed transmission line (CRLH-TL) structures are designed.

Unique properties of Ultra Wideband (UWB) radio, including very high data rate, low power consumption and low cost, make it a promising technology for fourth generation short-range wireless mobile communications. This paper introduces the reader to the UWB technology, to its main properties, capabilities and applications. Furthermore, the current status of regulatory issues of UWB radio transmi...

Ultra Wideband (UWB) is a new emerging and promising technology as it can accommodate higher data over a large bandwidth. we proposed a Printed Square-shape UWB Antenna With Dual Band-Notched Characteristics. A simple square patch antenna has been fed through a 50 Ω microstrip feedline .A rectangular notch has been etched on the ground plane to reject the interference of WIMAX Band (3GHZ-4.7GHZ...

This paper proposes a novel approach to reduce size and increase the impedance bandwidth of microstrip UWB (Ultra-Wideband) antenna, when using a thick substrate, so that it can be used for WPAN application, especially for mobile and portable devices.The application of gap-coupled capacitive feeding mechanism for achieving UWB with microstrip antenna has also been proposed.. The proposed antenn...

A compact printed ultra wideband (UWB) monopole antenna with multi-notched characteristics is presented. By inserting multiple E-shaped slot in micro strip feed line and ground plane, additional resonances are excited. The multi notch has been created by embedding a pair of – L shaped arm in the radiating patch and a modified E-slot defected ground structure in the feeding line. The designed an...

The advances in mobile technology, such as ultra wideband (UWB), enable the use of advanced applications in the process industry. The main challenge in the first phase of designing UWB networks and applications is getting to know what the process industry, i.e. the potential customer, wants. In this paper we present how we applied a user requirements elicitation process to get information about...

A method is presented which is aimed at increasing bandwidth of the tapered slot antenna by just finding the optimum tapering profile of the antenna without the need to increase its size rather than decrease. In this paper, an ultra-wideband (UWB) antenna with a compact size of 16 mm x 20 mm is proposed for USB dongle applications. Theproposed antenna has been designed on FR4 substrate dielectr...

This paper presents a simple yet very effective timedomain sparse representation and the associated sparse recovery techniques that can robustly capture raw ultra-wideband (UWB) synthetic aperture radar (SAR) records. Unlike previous approaches in compressed sensing for SAR, we take advantage of the sparsity and the correlation directly in the raw received pulses before even attempting image fo...

In this paper, an Ultra-Wideband (UWB) doubledirectional channel sounding measurement and spatio-temporal analysis of UWB propagation based on the clusterization approach were reported. After separating the propagation paths and diffuse components both on the transmitter (Tx) antenna and receiver (Rx) antenna positions, the propagation paths both on Tx and Rx positions were observed for cluster...

A subspace-based blind adaptive linear minimum mean square error (MMSE) detector has been proposed for multi-user detection in a direct sequence code-division multiple-access (CDMA) system even when multi-path channels are unknown. In this paper, the applicability of the subspace-based blind adaptive algorithm in multiple access ultra-wideband (UWB) systems is investigated. The problem of blind...
