A communication antenna amplitude and phase tester

Abstract

The invention discloses a communication antenna phase and amplitude tester, which comprises a rack, a first movement mechanism, a second movement mechanism, a tester and a controller, wherein the top part of the rack is provided with a soleplate, and a positioning mechanism is arranged on the soleplate; the first movement mechanism comprises a first screw rod arranged in the middle of the rack and parallel to a front and back direction, a first screw nut and a first motor, and a first support is fixed on the first screw nut; the second movement mechanism comprises a second screw rod arranged on the first support and parallel to a front and back direction, a second screw nut and a second motor, and the tail part of a cantilever is fixed on the second screw nut, and the head part is wound across the soleplate and extends above the soleplate; the tester is arranged at the head part of the cantilever; and the controller is used for controlling actions of the first motor and the second motor and receiving and processing test results of the tester. According to the tester of the invention, movement is steady, positioning is accurate, the test efficiency can be effectively improved, interference on the tester and the antenna by metal material can be effectively reduced, and accuracy of the test result is improved.

Description

technical field [0001] The invention relates to testing equipment for communication antennas. Background technique [0002] At present, the amplitude and phase of the communication antenna are usually tested manually, and the efficiency is low. A small number of test equipment will use some conveying structures to push the tester to move laterally above the antenna, so as to test the amplitude and phase of different positions on the antenna. , in these test equipment, the conveying mechanism and the mounting frame used to install the tester are generally set above the antenna and made of metal materials, and the metal material will interfere with the amplitude and phase test of the antenna and affect the accuracy of the test results Spend. Contents of the invention [0003] In order to solve the above problems, the purpose of the present invention is to provide a communication antenna amplitude and phase testing machine that can automatically perform amplitude and phase t...
