A novel coplanar waveguide (CPW) fed wide tapered slot antenna (WTSA) is presented in this paper. A wideband CPW-towide slotline (WSL) transition is employed to feed the antenna. The corrugated edge structure and broken line tapered profile are also applied in this design to achieve wideband performance, as well as maintain compact size. A prototype of the antenna is fabricated. The measured re...

The design of a compact metamaterial ultra-wideband (UWB) antenna with a goal towards application in microwave imaging systems for detecting unwanted cells in human tissue, such as in cases of breast cancer, heart failure and brain stroke detection is proposed. This proposed UWB antenna is made of four metamaterial unit cells, where each cell is an integration of a modified split ring resonator...

This is a revolutionary method which overcomes many of the antenna system analysis problems associated with UWB communication. By using this method, the antenna system is analyzed from the viewpoint of antenna to antenna transfer function, which makes it possible to consider the transmitting antenna and receiving antenna as a complete unit rather than individual element. The refined formulation...

A simple correlated channel model for ultrawideband (UWB) multiple-antenna systems is proposed. The authors show that a single numerical value of the spatial correlation coefficient is sufficient to accurately model the performance of UWB spatial multiplexing systems in an indoor environment. The appropriate value of the correlation coefficient is selected by ensuring a close match between the ...

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...

Fiber-to-the-antenna (FTTA) system can be a cost-effective technique for distributing high frequency signals from the head-end office to a number of remote antenna units via passive optical splitter and propagating through low-loss and low-cost optical fibers. Here, we experimentally demonstrate an optical ultra-wideband (UWB) - impulse radio (IR) FTTA system for in-building and in-home applica...

In this paper Electromagnetic Band Gap structure with microstrip antenna has been proposed. Many small and compact periodic EBGs have been investigated to design the antenna. Simulation is done on the HFSS software tool. The antenna is designed on the 21x31mm FR4 substrate with the dielectric constant of 4.4. The designed antenna is designed to resonate at 8GHz frequency. The designed antenna i...

UWB (U ̅ ltra-W ̅ ideB ̅ and) is a communications system that utilizes a bandwidth greater than 20% of the center frequency or at least 500MHz. It also uses extremely wide bandwidths ranging from hundreds of megahertz to several gigahertz. As shown in Fig.1, the output is less than the electromagnetic noise level of PCs; as such, conventionally used frequencies can be shared. The UWB provides the ...

A low-cost coplanar waveguide fed compact ultrawideband (UWB) antenna with band rejection characteristics for wireless local area network (WLAN) is proposed. The notch band characteristic is achieved by etching half wavelength C-shaped annular ring slot in the radiating patch. By properly choosing the radius and position of the slot, the notch band can be adjusted and controlled. With an overal...
