MEASURING CASE FOR RADIO WAVE EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To constitute in a small size by reducing an influence of a reflected wave. SOLUTION: A radio wave absorber 11 is mounted on an overall inner surface of a measuring case 17. An upper half of the case 17 is formed in a pyramidal state, a circularly polarized wave antenna 15 is mounted at its vertex, and a directing direction of the antenna 15 is brought into coincidence with a centerline of the pyramid. A small-sized radio wave equipment 13 to be measured is arranged at a disposing part 31 provided oppositely to the antenna 15. The antenna 15 is connected to a measuring instrument body 18 through a connector 17 and a cable 19. The pyramidal part 17a is openable and closable to a rectangular parallelepiped lower half 17b.
