A Low Disturbance Horn Antenna Bracket

Abstract

The invention discloses a low-disturbance horn antenna bracket, which is characterized in that it comprises a fixed bracket, a movable bracket and a disc clamp, the movable bracket is arranged above the fixed bracket, and a vertical track is arranged on the fixed bracket, and the movable bracket can move along the vertical The track moves up and down to adjust, the movable bracket is provided with a chute, the disc clamp is placed in the chute, the disc clamp can rotate in the chute, and the middle part of the disc clamp is provided with a mounting hole for installing the antenna. Antenna polarization conversion, installation and disassembly are convenient, and only one person is required to operate, which greatly saves manpower and test time, improves test efficiency, and improves measurement stability.

Description

technical field [0001] The invention relates to the technical field of electromagnetic compatibility testing, in particular to a low-disturbance horn antenna bracket. Background technique [0002] At present, high-power and high-frequency equipment on surface ships is gradually increasing, and the electromagnetic environment of surface ships is becoming more and more complex. In order to understand and control the electromagnetic environment of ships, the electromagnetic compatibility performance indicators of key equipment in ships should be controlled first, and Compatibility testing is the most effective means to discover equipment electromagnetic compatibility problems. The current test tasks are increasing rapidly, and the test efficiency needs to be greatly improved. Develop corresponding test brackets, connectors and other accessories, which can quickly move and replace antennas, facilitate the erection of various antennas in various test environments, and can also s...

Problems solved by technology

[0004] At present, multiple antennas are used in the field strength test. The shapes and weights of the antennas in different frequency bands are different, and the ways in which the antennas are installed on the brackets are also different. As a result, the current replacement of the antenna requires the cooperation of multiple people, and sometimes even requires the use of Special tools, time-consuming and labor-intensive

[0005] In addition, when the tripod is placed, the expansion angles of the three legs cannot be guaranteed to be the same, and the support points are not easy to balance, either high or low, and the metal materials used at the movable joints and bottom fulcrums affect the test accuracy, and the connection with the antenna is mostly 3mm to 4mm Screws, insufficient support strength, easy to break, and it is inconvenient to replace the antenna
