Abstract

The invention discloses a three-axis antenna scanning frame. The three-axis antenna scanning frame comprises a tripod; a transverse adjusting mechanism which comprises a transverse guide rail and a transverse adjusting seat, wherein the transverse guide rail is arranged on the tripod, and the transverse adjusting seat is slidably and adjustably arranged on the transverse guide rail; a longitudinal adjusting mechanism which comprises a longitudinal guide rail and a longitudinal adjusting seat, wherein the longitudinal guide rail is arranged on the transverse adjusting seat, the longitudinal adjusting seat is arranged on the longitudinal guide rail in a sliding adjusting manner, and the longitudinal guide rail is perpendicular to the transverse guide rail in direction; and an antenna fixing mechanism which is fixedly arranged on the longitudinal adjusting seat and is used for installing an antenna. Compared with the prior art, the repeated position switching and antenna installation and disassembly are avoided, the test efficiency and the reliability and stability of a measurement result are improved, and the problem that a whole space signal cannot be tested after one-time installation is effectively solved.

Description

technical field [0001] The invention relates to a three-axis antenna scanning frame, which belongs to the technical field of antenna supporting tools. Background technique [0002] Antenna scanning frames are often used when measuring space radiation signals in a specific area. However, at present, the antenna scanning frame is basically a fixed-point or one-way mobile device. If you want to test the space radiation signal, you need to change the antenna trajectory many times to achieve the purpose of measuring the radiation signal of a surface or a space. The method needs to move the scanning frame, loading and unloading the antenna multiple times, and move the position, the test efficiency is low, and the accuracy error becomes larger when the position is changed, so that the error of the measurement result increases accordingly. Contents of the invention [0003] Based on the above, the present invention provides a three-axis antenna scanning frame to solve the problem...
