Abstract

Microcellular communication networks such as the personal handy phone system (PHS), polarization diversity reception is used to reduce multipath fading. It is also effective to increase the average signal in the up-link from the hand-held terminals because the horizontal polarization is dominant. When a polarization diversity antenna is used for a indoor base station, geometric low profile and monopole radiation pattern are required because the antenna is mounted on the ceiling. This paper presents a notch-wire composite antenna as a low profile polarization diversity antenna. A three-notched circular disk antenna and a wire antenna are proposed as element antennas. The characteristics of the composite antenna are evaluated using the method of moment with the thin wire approximation, and the desired monopole radiation pattern and small mutual coupling are confirmed.
