PURPOSE: An antenna radiation power measurement device and a method are provided to measure a radiation power of a large size high gain antenna in a small or a middle sized chamber which does not satisfy a far field condition. CONSTITUTION: An antenna radiation power measurement device comprises a chamber (100), a source antenna (105), a test antenna (107), a rotation axis (109), and a roll positioner (111), and a turn table (115). The chamber attaches an absorber to a wall. The source antenna and the test antenna are arranged inside the chamber. The rotation axis controls an arrangement angle of the test antenna upward and downward. The roll positioner rotates the test antenna around the rotation axis, and controls the arrangement angle upward and downward. The turn table rotates to a right and a left direction which cross at right angles to an upper and a lower direction inside the chamber. |
