Abstract

Aim of this contribution is to study the impact of typical ultra-wideband (UWB) antennas for communications over a spatial wireless channel. In order to adequately consider the directivity properties of real antennas, out analysis is suitably based on a ray tracing UWB channel model since this reflects the dependence on the angle of arrival (AoA) and angle of departure (AoD) of any multipath. A mathematical framework is given which also allows an optimization of such an UWB multiple input multiple output (MIMO) system using different types of transmitting and receiving antennas on behalf of idealistic omnidirectional ones. Beside the angle dependence, the antenna transfer functions are without doubt frequency dependent on such a large UWB bandwidth, so that they will be evaluated with suitable analog design specialized tools for the fast and accurate three-dimensional electromagnetic simulation of high frequency circuits. Simulation results allowing concrete guidelines on the antenna influence are provided in the last section of this paper

超宽带天线对空间信道通信的影响

这项贡献的目的是研究典型的超宽带(UWB)天线对空间无线信道通信的影响。为了充分考虑真实天线的方向性特性，输出分析基于射线追踪UWB信道模型，因为该模型反映了任何多径的到达角(AoA)和出发角(AoD)的依赖性。给出了一个数学框架，该框架还允许使用代表理想全向天线的不同类型的发射和接收天线对这种超宽带多输入多输出(MIMO)系统进行优化。除了角度依赖之外，天线传递函数无疑也依赖于如此大的UWB带宽，因此它们将使用合适的模拟设计专用工具进行评估，以便快速准确地进行高频电路的三维电磁仿真。本文的最后一节提供了对天线影响给出具体指导的仿真结果
