Abstract :
A comparison of ultra-wideband (UWB) and 60 GHz channels inside a car is carried out in this paper. Measurements with a vector network analyzer (VNA) in the frequency bands of 5–8.5 GHz and 67–70.5 GHz have been carried out and the large-scale and small-scale parameters have been investigated. The results are shown for different antenna configurations and polarizations as well as for an empty car and a car occupied with persons. Furthermore, a link budget analysis for both systems based on the measurements is carried out.
