Influence of antenna radiation patterns on MM-wave indoor radio channels

In millimeter-wave indoor radio systems the radiation patterns of the applied antennas at the remote and base station have considerable impact on received power and channel dispersion and therefore on the performance of indoor radio communication systems. This influence is examined by simulating the high frequency propagation behavior in a typical indoor environment by using a propagation model according to Geometrical Optics. First, the accuracy of this propagation model is tested by comparing initial simulation results with measurement data obtained from a large scale measurement campaign which has been carried out in various buildings of the Eindhoven University of Technology. Next, sectoral horn antennas as well as biconical horn antennas are considered in different setups and the dependence of normalised received power and RMS delay spread on beam directivity, pointing error and wall reflectivity under both line-of-sight and non-line-of-sight conditions is determined.
