PROBLEM TO BE SOLVED: To provide a primary radiator which allows for easy and highly accurate attachment of an antenna to a wave guide, and to provide a radio wave receiver including the same.SOLUTION: The primary radiator of a radio wave receiver includes an antenna substrate and a wave guide. An antenna is provided on the antenna substrate, and the wave guide has an internal space where radio waves propagate. At least a part of the antenna is disposed in the internal space. The wave guide also has a holding section for holding the antenna substrate. The holding section regulates the attachment position of the antenna substrate for the wave guide, in the propagation direction of radio waves and a direction perpendicular thereto.SELECTED DRAWING: Figure 3 |
