Abstract

This paper presents an early stage of developing an
outdoor propagation model in millimetre wave bands and
consider developing electrical parameters for building materials
at 45GHz. Sample materials for building have been chosen for
investigation in term of diffraction and attenuation as a mean of
extracting true attenuation properties. Results for diffraction are
validated against a Knife Edge Diffraction model; the effect of
the sample size/thickness investigated and finally the attenuation
for both concrete and wood sample are presented, showing
concrete attenuation at 4.38 dB/cm and solid wood at 2.42 dB/cm
at horizontal-horizontal polarization and at vertical–vertical
polarization of 4.64 dB/cm and 4.19 dB/cm respectively. Towards
the end of this research, the materials parameters will be
embedded in a 3D ray tracer simulator for outdoor propagation
modelling.
