Indoor-to-Outdoor Path Loss Measurements in an Aircraft for Terahertz Communications

In this paper, measurements of the attenuation by the window and fuselage of an aircraft for Terahertz communications are presented. The measurements are performed at 300GHz using an ultra wide-band sub-mmWave channel sounder in a Boeing 737. They are subdivided into a characterization of perpendicular and oblique incidence, respectively, with regard to the azimuth angle. Before presenting the results, the different measurement setups are described. The results suggest a minimal attenuation of -11.01 dB by the window for perpendicular incidence whereas no specific angle dependency could be identified.
