Abstract (in Japanese) (See Japanese page) 
(in English) In this paper，we perform ray tracing propagation analysis considering with multi-beam antenna to investigate the effect of multi-beam antenna due to base station antenna height in small wireless area. The horizontal antenna pattern is considered 4 multi-beams by Butler matrix circuit. The base station antenna height is higher or lower than average building height in urban area. Consideration different beam width cases， we compare received powers in LOS(Line of Sight) or NLOS(Non LOS) from the base station
when 4 multi-beams are radiated. According to the analysis results，when the base station antenna height becomes lower than the average building height in LOS，the antenna pattern in the free space is hard to preserve，however it is shown that the tendency of preserving the antenna patterns of each beam is similar.
