“…Simulations are executed in conditions which are 1, 2 and 4 transmit antennas at data rate 320, 400 and 480 Mbps. In the case of 4 transmit antenna, data rate is 3/4 that is confirmed from (4). Simulation results show that multi-antenna systems have the better performance than single antenna system and also as the number of antennas increases, the system has the better BER performance.…”

“…The UWB has attracted considerable interest in the research and standardization communities, due to its promising ability to provide high data rate at low cost with relatively low power consumption [1][2][3][4][5][6]. In the UWB communication, the data rate must be high enough (greater than 110 Mb/s) to satisfy a set of multimedia industry needs for wireless personal area networks (WPAN) communication, and the quality of service (QoS) capabilities are required to support multimedia data types.…”

Abstract-In this paper, the channel estimation in multi-band OFDM (MB-OFDM) ultra-wideband (UWB) based multiple-antenna transmission systems is studied. For multiple antennas, each preamble designed by the Zadoff-Chu sequence satisfies the orthogonal property in the time domain. Therefore, the proposed preambles can improve the system performance and be applied to MB-OFDM specification in the case of more than two transmit antennas.

Abstract-Gaussian process (GP) regression is proposed as a structured supervised learning alternative to neural networks for the modeling of CPW-fed slot antenna input characteristics. A Gaussian process is a stochastic process and entails the generalization of the Gaussian probability distribution to functions. Standard GP regression is applied to modeling S 11 against frequency of a CPW-fed secondresonant slot dipole, while an approximate method for large datasets is applied to an ultrawideband (UWB) slot with U-shaped tuning stub -A challenging problem given the highly non-linear underlying function that maps tunable geometry variables and frequency to S 11 / input impedance. Predictions using large test data sets yielded results of an accuracy comparable to the target moment-method-based full-wave simulations, with normalized root mean squared errors of 0.50% for the slot dipole, and below 1.8% for the UWB antenna. The GP methodology has various inherent benefits, including the need to learn only a handful of (hyper) parameters, and training errors that are effectively zero for noise-free observations. GP regression would be eminently suitable for integration in antenna design algorithms as a fast substitute for computationally intensive full-wave analysis.

“…According to the sanction of civil UWB in 3.1-10.6 GHz formulated by U.S. federal communications commission (FCC), researchers have proposed a lot of UWB antenna designs, which mainly focus on various flat heterotype monopole antennas, including circular disc monopole antenna [1], elliptical monopole antenna [2], and different polygonal monopole antennas [3][4][5]. In addition, these monopole antennas are fed by coplanar waveguide (CPW) [6] and microstrip line [7,8]. However, studies on UWB dipole antenna attract less attention than the monopole.…”

Abstract-A novel wafer-dipole printed antenna fed by balanced microstrip line is proposed, and the adoption of the balanced microstrip line can effectively solve the feeding problem of the UWB dipole antenna. The wafer-dipole and a branch of the balanced microstrip line are printed on one side of FR-4 substrate (1 mm thickness), and the later is connected to a wafer directly, while the other branch is printed on the back side and connected to the other wafer with a via-hole. The measured results show that the antenna impedance bandwidth is from 3.0 GHz to 15.0 GHz with VSWR < 2, and the ratio bandwidth is about 5 : 1. Moreover, the antenna size is just 40 mm × 20 mm with simple structure, which is well suited for short-distance UWB communications.
