Infrastructure-Aided Localization with UWB Antenna Arrays
This paper presents an approach for a precise 2D-localization of a mobile station in indoor scenarios by one single base station only. In the approach both, the Direction of Arrival (DoA) and the Time of Arrival (ToA), are estimated using UWB beamformers at both sides of the link. The article describes the algorithm, as well as the required hardware. A duallinear polarized, directive UWB antenn...
متن کاملUWB Ring Filter and UWB Plane Antenna
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 ...
متن کاملSpatial Focusing Characteristics of Time Reversal Uwb Pulse Transmission with Different Antenna Arrays
Spatial focusing characteristics of time reversal (TR) electromagnetic waves are studied in this paper. Different antenna arrays are used as a TR mirror and their elements are arranged in one and two dimensions in the horizontal plane. The focused energy density around initial source location is investigated in non-line-ofsight (NLOS) and line-of-sight (LOS) cases, respectively. The results dem...
متن کاملUWB Antenna Array with Comb Taper Slot Antenna Elements
A uniformly spaced comb taper slot antenna array is proposed for directional ultra-wideband (UWB) applications. The UWB array consists of four identical comb taper slot antennas, a mutistage with four-way microstrip UWB power divider, and four identical coaxial cable lines. A maximum gain of 15.5dBi within the band is obtained when the element separation is properly selected. The uniform spacin...
متن کاملUWB Spiral Antenna with Parabolic Reflector
A cavity-backed spiral antenna with ultra-wide band width is presented. By using a parabolic reflector, the radiation of the antenna becomes uni-directional, and the gain is promoted. The antenna is fed by a coaxial cut-away balun with fan-shaped patch which keeps a wideband impedance matching. The simulated bandwidth for VSWR < 2 covers 0.36 ~ 6.83GHz or bandwidth ratio of 19:1, and the gain a...
