Abstract

The invention relates to a universal antenna flange, which includes a disc body with a central protruding shaft, at least one antenna interface plate is extended on the outer edge of the disc body, and the plane where the antenna interface plate is located An obtuse angle structure is formed between the plane of the disk body, the antenna polarization axis of each antenna interface board intersects with the central axis of the disk body at the same focal point, and the outer edge of the central convex axis of the disk body corresponds to each antenna interface board A positioning hole is provided, and the center of the positioning hole is located on the projection line of the antenna polarization axis of the corresponding antenna interface board on the disk; a universal antenna conversion device includes a universal antenna flange and a scanning frame , the flange plate can be rotatably connected to the slope of the scanning frame; the invention solves the problem of simple switching of various probe antennas under test in the quiet zone test of the compact field, and at the same time improves the working efficiency and reliability of the quiet zone detection.

Description

technical field [0001] The invention relates to a flange device, in particular to a universal antenna flange and an antenna conversion device containing the flange. Background technique [0002] The compact field is a device that uses a precise reflector or microwave lens to convert the spherical wave emitted by the feed source into a plane wave within a short distance. The quasi-plane wave generated by it can fully meet the environmental requirements of the antenna, radome electromagnetic characteristics and target RCS test . [0003] Usually, the probe scanning method is used to calibrate the performance of the quiet zone in the tight field, and the standard probe antenna is used to directly test and evaluate the amplitude and phase of the plane wave field in the tight field test area. [0004] see Figure 1-Figure 10 As shown, the frequency coverage of the compact field test is from 0.3GHz to 40GHz, and the frequency band is very wide. One antenna cannot cover the entire...
