<P>PROBLEM TO BE SOLVED: To improve a measurement efficiency by reducing measurement time of an antenna characteristic. <P>SOLUTION: A measurement point scanning section scans a measurement point. An antenna gain measurement section measures antenna gains for every plural measurement points, and a reference point is set from whole measurement points to obtain an antenna gain differential value which is a difference between the antenna gain on the reference point and the antenna gain on other measurement points. An antenna characteristic measurement section measures a reference antenna characteristic which is the antenna characteristic on the reference point. The reference antenna characteristic is corrected by the antenna gain differential value to obtain the antenna characteristic on the other measurement points. <P>COPYRIGHT: (C)2012,JPO&INPIT |
