PURPOSE:To prevent the deterioration in the basic performance by fitting freely attachably and detachably an inspection waveguide device to the irradiation face of an active array antenna. CONSTITUTION:A fitting metal fixture 14 fitting freely attachably and detachably the inspection waveguide device 12 to the radiation face of an array antenna 5 is fitted to the inspection waveguide device 12 comprising the array antenna 5 consisting of the arrangement of element antennas 51...5n and waveguide lines 101...10n. The array antenna 5 is in use by removing the inspection waveguide device 12 from its radiation face by using the fitting metal fixture 14 normally. In requiring to check the output, the inspection waveguide device 12 is mounted by using the fitting metal fixture 14 as shown in figure. |
