RADIATION ELECTROMAGNETIC FIELD MEASURING SYSTEM AND RADIATION ELECTROMAGNETIC FIELD MEASURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a radiation electromagnetic field measuring system and a radiation electromagnetic field measuring method capable of measuring efficiently a radiation electromagnetic field, even when a semi-anechoic chamber is small.;SOLUTION: This radiation electromagnetic field measuring system 1 for measuring a radiation electromagnetic field on a position separated from a specimen 20 as far as a measurement distance includes: a semi-anechoic chamber 2 having a floor surface part 2a, lengthwise shield wall parts 2b, 2c, shortwise shield wall parts 2d, 2e, and a shield ceiling part, wherein an electromagnetic field absorber 3 is installed on the inside thereof; a turn table 4 arranged on a position at an approximately equal distance respectively from the lengthwise shield wall parts 2b, 2c; a receiving antenna 8c arranged movably in the vertical direction between a lengthwise center line C_L and the lengthwise shield wall part 2b; a receiving antenna 9c arranged movably in the vertical direction between the lengthwise center line C_L and the lengthwise shield wall part 2c; and a spectrum analyzer for measuring each reception intensity of the receiving antennas 8c, 9c, respectively.;COPYRIGHT: (C)2011,JPO&INPIT
