PURPOSE: To reduce production cost and characteristic dispersion accompanying the reduction in the number of parts. CONSTITUTION: Circuit parts 3, 6, 7, 8, 9,... such as a dielectric rod 3 are fixed on an upper conductor plate 2 and a lower conductor plate 1 and a secondary radiator 5 are integrally formed. The circuit parts 3, 6, 7, 8, 9,... are fixed on the plate 2 by using a temporary lower conductor plate 1' and the performance of an NRD radar module formed by the fixing of the circuit parts is inspected (C). Almost simultaneous with the fixing of the circuit parts, the plate i integrated with a secondary radiator 5 is formed, and after the end of the performance inspection, the plate 2 fixing the circuit parts are removed from the plate 1' and fixed on the final lower conductor plate 1 integrated with the secondary radiator 5. |
