N2 - The Personal Handy-phone System (PHS) has been in operation in Japan since 1996, and various antennas for the PHS base station have been used. For the base station antennas, rod antennas are widely used, because of their ease of installation and low cost. They are generally installed on the top of public telephone boxes, on street utility poles, or on the roof of buildings. One such antenna is the vertically polarized collinear antenna with bi-directional radiation pattern in the horizontal plane. This antenna is suitable for street microcells used for low base station antennas in urban areas. On the other hand, the handsets are commonly used in tilted angle, therefore the horizontal polarization is dominant in the up-link. Then, the polarization diversity reception at the base station is expected to increase for the up-link level. In this paper, we investigate propagation characteristics under the street environment by using the bi-directional polarization diversity antenna as a base station antenna.
