ELECTRIC WAVE ABSORBER MEASURING JIG AND MEASURING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To enhance the easiness of sample loading and measuring accuracy. SOLUTION: This measuring jig comprises: an outer conductor 12, having a cross section in the form of a rectangle that is 400 mm×600 mm and having a cylindrical part 12b taking the form of a rectangle that is also 400 mm×600 mm and integrated with the open end of a hone-antenna-shaped part 12a gradually spreading from a coaxial connector 16 while keeping that ratio as does a hone antenna; a short-circuit board 14 in which a metallic thin inner conductor 13 electrically insulated from the outer conductor 12 is placed in a position dividing the insides of both the hone-antenna-shaped part 12a and the cylindrical part 12b of the outer conductor 12 into two equal parts, and which causes an electric short circuit on the end faces of the outer conductor 12 and the inner conductor 13 in order to load and evaluate a sample; a closing door 15 equipped with a spring mechanism, for installing and removing the sample and for completing contact with the outer conductor 12; and an N-type coaxial connector 16 for applying a TEM wave between the outer conductor 12 and the inner conductor 13.
