PROBLEM TO BE SOLVED: To provide a shield box with built-in directional antenna wherein installation coordinate position and RF bonding loss of portable telephone terminal with other types are approximated, a measurement table in a shield box is miniaturized and an RF banding lass compensating amplifier of a measurement device is simplified. SOLUTION: A measurement table 3 of insulation material is housed in a shield box 1 formed out of electric wave absorber 2, and on the measurement table 3, a sample portable telephone terminal 4 is mounted on a measurement coordinate position, and a dipole antenna 5 with reflecting plate provided with an antenna element 5a and a reflecting plate 5b is assigned under the measurement table 3, and electric wave emitted by the portable telephone terminal 4 is received with a dipole antenna 5 with reflecting plate, and the output is measured with a measurement device through a feeder line 6 and a connector 7. |
