Abstract

Ultra-wideband (UWB) technology is being proposed for several short range wireless applications. Some of the applications, such as position location devices for rescue personnel, may require the antenna height to be close to the ground. In scenarios where the antenna height is very low (from 0 to 30 cm), propagation characteristics and channel modeling are needed to provide important insights for the application design. This paper presents time-domain measurements and channel characterization of the indoor UWB channel at three different antenna heights (7.5 cm, 26.5 cm, and 108.5 cm). The transmitting and receiving antennas are placed at heights referred to as near ground, middle ground, and above ground. The effects of the antenna height on the channel characteristics are analyzed. Both large and small-scale characteristics are evaluated and the results for different antenna heights are compared. The results show that large scale characteristics exhibit monotonic behavior with respect to antenna height while small scale characteristics do not follow this behavior. The possible explanations for the obtained results are also discussed.

天线高度对室内超宽带信道特性的影响

超宽带(UWB)技术被提出用于几种短距离无线应用。某些应用，例如救援人员的位置定位设备，可能要求天线高度接近地面。在天线高度非常低(从0到30厘米)的情况下，需要传播特性和信道建模来为应用设计提供重要的见解。本文介绍了三种不同天线高度(7.5厘米、26.5厘米和108.5厘米)下室内超宽带信道的时域测量和信道特性。发射天线和接收天线的高度分别为近地、中地和地面以上。分析了天线高度对信道特性的影响。对天线的大、小尺寸特性进行了评估，并对不同天线高度下的结果进行了比较。结果表明，大尺度特性对天线高度表现出单调性，而小尺度特性则不遵循这种特性。对所得结果的可能解释也进行了讨论。
