In this report the authors presnet the initial investigation of the principal propagation mechanisms in the urban radio channel for co- and cross polar antennas. It is widely believed that dominant propagation mechanisms are identical for all polar combinations even though no firm evidence for this has been delivered. In fact the experimental study of polar urban propagation channel is scarce in the open literature. In the current study we employ the data obtained from a set of measurements at 2.2GHz in two locations of Tokyo metropolitan areas and one location in Yokohama city for three different base station antenna heights. The received azimuth- and elevation-power-spectra at the mobile terminal (MT) are analyzed with regard to the street direction for all combinations of the transmitter (Tx) and receiver (Rx) antenna polarizations. The directional copolar ratio (CPR) and cross polar ratio (XPR) are also presented.
