産効率を高めるという効果を有する。As explained above, the method for manufacturing a flat antenna storage case according to the present invention has the following special effects. (1) Since the side surfaces of the case are set parallel to each other, the planar antennas fixed to the side surfaces of the case are maintained parallel to each other, making it easier to reproduce the expected directivity characteristics. This has the effect that directional characteristics can be easily realized. (2) By manufacturing the side surface of the case by pultrusion molding, it can be relatively freely adapted to any cross-sectional shape as long as it has a hollow polygonal column shape, which has the effect of dramatically improving the degree of freedom in shaping. (3) Since pultrusion molding as a means for forming the side surface of the case can be performed continuously, the case can be manufactured easily and has the effect of increasing production efficiency.
