Abstract:
1. An antenna radiation pattern measurement device that measures a radiation pattern of an antenna under test (AUT) by using a source antenna, comprising: a control unit for controlling driving of the source antenna and the AUT; an analysis unit for measuring an electric field value from a radio frequency (RF) signal that is transmitted from the source antenna and received by the AUT or transmitted from the AUT and received by the source antenna; and a measurement unit for controlling the control unit to drive the source antenna or the AUT to a plurality of positions, controlling the analysis unit to measure electric field values at the plurality of the positions, and determining a radiation pattern of the AUT by using the electric field values measured; wherein the analysis unit measures the electric field value at a plurality of points corresponding to the plurality of positions, while maintaining a distance between the source antenna and the AUT by a first length, and the measurement unit determines a radiation pattern at a region at a distance of a second length from the AUT by using the electric field values at the plurality of points and a value corresponding to a ratio between the first length and the second length; and wherein the value corresponding to a ratio between the first length and the second length is expressible as where R
