On The Effect of Antenna Height On the Characterization of The Indoor UWB Channel Umesh K. Shukla, Haris I. Volos, and R. Michael Buehrer Wireless@Virginia Tech Blacksburg, VA 24061, USA Email: {ushukla, hvolos, buehrer}@vt.edu Abstract—Ultra-wideband (UWB) technology is being pro- be an important application as described in [3]. As it will be posed for several short range wireless applications. Some of shown, not all the channel characteristics for this height can the applications, such as position location devices for rescue be directly inferred from the characteristics of the other two personnel, may require the antenna height to be close to the ground. In scenarios where the antenna height is very low (from heights. Second, [8] lacks in providing explanations for the 0 to 30 cm), propagation characteristics and channel modeling are obtained results, especially for the small scale characteristics needed to provide important insights for the application design. (SSC). This paper presents time-domain measurements and channel The contribution of this paper is to complement [8] by characterization of the indoor UWB channel at three different addressing the issues mentioned above. The use of three dif- 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 ferent antenn
