Apparatus for Antenna Alignment for Near-Field Measurement

摘要

1. the art that the invention defined in the claims; The present invention will on the antenna matching device for Near Field measurements.; 2. The invention attempts to solve the technical challenges; The present invention, by using an antenna pattern to be measured that aims to provide an antenna matching unit for, Near Field measurements to perform the correct match between the measuring antenna and the probe antenna by detecting the coordinates of a minimum of the error.; 3. Resolution of the subject matter of the invention,; The present invention, in the antenna matching device for Near Field measurements, receiving for receiving a signal transmitted from an external antenna measurement antenna; Signal dividing means for dividing the signals received at the receive antennas in the vertical and horizontal polarization; Vertically polarized wave receiving means for receiving a vertically polarized wave split by the signal splitting means; Horizontally polarized wave receiving means for receiving a horizontally polarized wave split by the signal splitting means; A first amplitude / phase detecting means for detecting the amplitude and phase of the signals received from the vertically polarized wave receiving means; A second amplitude / phase detecting means for detecting the amplitude and phase of the signals received from the horizontally polarized wave receiving means; To the receiving antenna matching in accordance with the polarization of the measuring antenna, and the coordinates of the first compares the amplitude / phase detection in the amplitude / phase and said second amplitude / phase detecting means detected by the amplitude / phase detecting means coordinate determining means for determining; And also according to the determined coordinates in the coordinate determining means includes a position adjusting means for adjusting the position of the receiving antenna.; 4. An important use of the invention,; The invention yiyongdoem etc. Near Field antenna measurement system.
