Title:
RADIO WAVE TRANSPARENCY MEASUREMENT DEVICE
Document Type and Number:
Japanese Patent JP2018042163
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To reduce the diffraction or the wraparound of a radio wave caused by a measurement device and measure a radio wave transparency of a member at precisely.SOLUTION: A radio wave transparency measurement device 10 that measures a radio wave transparency of a member P, comprises: a supporting part 12 that supports the member P; a transmission part 14 that transmits a radio wave under a predetermined condition for an incidence surface F1 of the member P; and a measurement part 16 that measures the radio wave penetrated to a surface F2 opposite to the incidence surface F1 of the member P. A radio absorptive material 20 is arranged on the surface opposite to the transmission part 14 of the supporting part 12, and prevents influence by the radio wave achieved to the supporting part 12 from being reflected to a direction of a measurement part 16 and applied to a measurement result.SELECTED DRAWING: Figure 1
