DIRECTIVITY MEASURING POSITIONER FOR SMALL WIRELESS DEVICE AND THE LIKE

摘要

PROBLEM TO BE SOLVED: To provide a positioner for evaluating performance for any using posture normally postulated, for a portable small wireless device and the like. SOLUTION: The positioner is constituted to measure the directivity of radiated power and the like of test machines, such as a small wireless device with an operation frequency over ultrahigh frequency zone. The positioner is also constituted of foaming resin material and is made possible to scan in three-axial directions of the test machine contained in the positioner. The rotation for scanning the three-axis directions includes self-rotation of the test machine containing cylinder, a rotation for scanning the elevation direction of the test machine containing cylinder and the rotation for scanning the azimuth direction of the test machine containing cylinder.
