“…The Federal Communications Commission (FCC) and the International Telecommunication Union Radiocommunication sector (ITU-R) define Ultrawideband (UWB) as an antenna transmission for which the emitted signal occupies a fractional bandwidth greater than 0.2 or a bandwidth more than 500 MHz. Thanks to its several attractive properties, UWB technology has seen tremendous advances in the field of wireless communications [1], imaging [2], radar [3], networking [4], and localization [5]. For instance, the large bandwidth allows for more reliable communications by providing a high resilience to frequency selective fading.…”

Ultrawideband (UWB) has the ability to achieve decimetre level of ranging accuracy, hence, its wider usage nowadays in the field of positioning. In spite of the attractiveness of UWB, its performance is strongly dependent on the propagation channel. In this paper, an analysis of the the UWB channel for ranging applications using an inhouse developed 3D Ray launching (3D RL) algorithm is presented. A parametric study has been performed considering variations of cuboid size resolution of the simulation mesh, in order to analyze convergence impact on estimation accuracy, focusing on Radio frequency (RF) power levels as well as time domain characterization. The RF power results have been used to model the path-loss, small scale fading, and the power delay profile so as to obtain the statistics of the multipath channel as well as time of flight (TOF) estimation values. The results show that the 3D RL is a valuable tool to test UWB systems for ranging applications with a mean accuracy of up to 10 cm in multipath conditions considering complex scatterer distributions within the complete volume of the scenarios under test.INDEX TERMS Ultrawideband, 3D ray launching, time of flight, ranging, channel modelling, radio frequency power levels.

In this paper, ultrawide band (UWB) communication systems with eight transmitting and receiving ring antenna arrays are implemented to test the bit error rate and capacity performance. By using the ray-tracing technique to compute any given indoor wireless environment, the impulse response of the system can be calculated. The synthesized beamforming problem can be reformulated into a multiobjective optimization problem. Self-adaptive dynamic differential evolution (SADDE) and particle swarm optimization (PSO) are used to find the excitation current and the feed line length of each antenna to form the appropriate beam pattern. This pattern can then reduce the bit error rate and increase the channel capacity and receiving energy. Numerical results show that the fitness value and the convergence speed by the SADDE are better than those by the PSO. Moreover, the SADDE had better results for both line-ofsight and nonline-of-sight cases. In other words, compared with PSO, SADDE has improved more effectively the main beam radiation energy and reduced the multipath interference.

“…On-chip integrated antennas allow avoiding external communication lines and sophisticated packaging, minimizing the total footprint and losses. In particular, they represent a good solution for short-distance ultra-wideband (UWB) communications, up to 10 cm [4], [5]. However, a trade-off has to be found between size, bandwidth and efficiency, especially when the antenna dimensions become smaller than the wavelength.…”

In this paper, measurements and simulations of miniature monopole antennas for ultrawideband (UWB) GHz intra-and inter-chips communication and biomedical applications are presented. Folded designs on four substrates are studied: 1) standard bulk; 2) high-resistivity bulk; 3) ultra low-loss radiofrequency silicon-on-insulator (RF SOI); and 4) quartz. Among the Si-based substrates, RF SOI with its trap-rich sublayer demonstrates the best performances with the lowest RF power losses and centimetric transmission distance between antennas. Transmitted power between two antennas was measured from 0.01 to 20 GHz. Using substrate characterization of resistivity, permittivity, and loss tangent based on measured coplanar waveguide lines on the same substrates, good agreement is obtained between the return losses of simulated antennas on each substrate and numerical solutions, confirming the impact of the substrate properties. An antenna bandwidth of 680 MHz is demonstrated at 6.0 GHz meeting the criterion for UWB radio communications in the 6-10 GHz band.
