ANTENNA POSITIONER, UNNECESSARY RADIATION ELECTROMAGNETIC WAVE MEASUREMENT SYSTEM AND UNNECESSARY RADIATION ELECTROMAGNETIC WAVE MEASUREMENT METHOD

摘要

PROBLEM TO BE SOLVED: To provide an inexpensive antenna positioner capable of easily changing a height, an angle of depression and a polarization angle of an antenna, and having high measurement accuracy and measurement stability, and provide an unnecessary radiation electromagnetic wave measurement system and an unnecessary radiation electromagnetic wave measurement method.;SOLUTION: An antenna positioner comprises: a columnar body; a liftable body lifting/lowering along the columnar body; an antenna mounting arm mounted rotatably around a horizontal axis with respect to the liftable body; and an antenna adapter having an antenna mounting part, and mounted rotatably around a central axis of the antenna mounting part with respect to the antenna mounting arm. The antenna positioner can change a height of the antenna mounting part, an angle of depression of the antenna mounting part and a rotational angle around the central axis of the antenna mounting part, only by lifting/lowering the liftable body.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
