Design of Wideband Waveguide Hybrid With Ultra-Low Amplitude Imbalance

Coplanar Waveguide-fed RectangularSlotAntennafor Ultra-Wideband Application

This study describes a tunable coplanar waveguide fed (CPW) rectangularslot antenna to work within ultra wide band (UWB) for the future communication systems. This slot antenna of area 30*20mm is designed on a FR4 substrate and its operation was tested in terms of return loss and gain. The developed antenna shows VSWR  2 bandwidth of 800MHz in 0.7-1.51GHzband as well as bandwidth of 6.06GHz in...

Design of Low Noise Amplifier for Ultra-Wideband Applications

The recent surge in the demand for low power portable wireless electronics that can offer extremely high data rates has resulted in much active research in Ultra-Wideband (UWB) systems. UWB is widely recognized as a promising technology for high data rate, short-range applications with precise time resolution and high energy efficiency. All these benefits originate from the wideband characteris...

Rapid Hybrid Acquisition of Ultra-Wideband Signals

Impulsive ultra-wideband (UWB) radio provides many promising features for wireless communications in a dense multipath environment. However, these features are largely the result of the enormous effective processing gain, which can make acquisition difficult at the receiver. In this paper, a recently developed theory of minimum complexity sequential detection is applied to the hybrid acquisitio...
