| Abstract(in English) | It is known that a narrow beam antenna, which is smaller than the base station 's sector angle, is effective for IMT-2000 system. As the capacity will increase, it will need to replace antennas with those of narrow,beam in horizontal plane. Replacement of antennas becomes necessary and will be economically inferior with causing the interruption of service. In order to solve these problems, this paper shows that installation of metal conductors adjacent to 60-degree beam antennas narrows the HPBW in horizontal plane by using moment method analysis. |
