Abstract

Measurements of multipath-propagation characteristics were conducted at 60 GHz in a room within in a modern office building. Delay profiles were measured by a swept frequency method with a high time-delay resolution of 2 ns. Direction-of-arrivals of the multipath components reflected from walls analyzed by rotating a narrow-beam receiving antenna with an angular resolution of 5 degrees. As a result of this experiment, it was found that multipath delayed waves due to wall reflections can be effectively suppressed by employing circular polarization instead of linear polarization. Based on this experimental result, a computer simulation was made to make clear the polarization dependence of the high-speed transmission characteristics of a indoor communications system operating at 60 GHz
