title = "Wideband 39 GHz Millimeter-Wave Channel Measurements under Diversified Vegetation",
abstract = "This paper presents a measurement-based analysis of 39 GHz millimeter wave (mm-wave) radio propagation through vegetation using an ultra-wideband (UWB) channel sounder. The measurement campaign was conducted in a suburban area on campus of Tongji University, Shanghai, China. Two different kinds of measurements were performed to investigate the foliage influence on the characteristics of radio propagation in the mm-wave bands. A direction-scan sounding (DSS) approach was used in the measurements aiming to explore the vegetation attenuation as well as dispersive characteristics of the propagation channel. Approximately 6.7 to 8.7 dB single-tree attenuation and 1.86 to 2.23 dB/m vegetation attenuation were observed at the so-called boresight aligned direction (BAD) of a transmitter (Tx) and a receiver (Rx). The presence of vegetation leads to dispersion in delay and angular domains. Both delay spread and azimuth of arrival spread were proportional to the number of trees existing between the Tx and the Rx. Measurements with the purpose of investigating the relationship between the foliage loss and Tx/Rx distances away from trees were also conducted.",
