On-roof wireless link operating at 60 GHz

The paper discusses possible ways of building a wireless link along an inner part of a roof of a car at 60 GHz. The investigation is mainly based on experimental measurements. A vector network analyzer, horn antennas integrated into substrate and open-ended rectangular waveguide antennas are key components of measurement setup. For an appropriate positioning of the antennas and an adjustment of used materials, suggested mechanical equipment was designed to improve repeatability of measuring the transmission coefficient.
