Description

Technical Field

[0002] In a compact field, the feed source generally emits a spherical wave, which is reflected by the reflecting surface to form a plane wave. Usually, the quiet zone refers to the area where the amplitude, phase, cross-polarization and other indicators of the formed plane wave have good characteristics. In other words, the compact field method can simulate a better plane wave in a very small field, and can be directly used for electromagnetic testing without mathematical conversion, and has gradually become the mainstream test method for 5G antenna testing.

[0003] At present, micro-compression fields at home and abroad often adopt an integrated structure, and the types of test items are different. The general compression fields have relatively uniform types of test items and relatively small test limitations, resulting in relatively low efficiency and relatively high costs. Therefore, we proposed a mechanical accuracy detection device for the reflective surface of a compression field. Utility Model Content

By setting a threaded rod, a support table is moved upward or downward through a sliding groove on the left side of the inner wall of the outer box of the compression field, and then the support table is adjusted at the support height to prepare for testing, thereby ensuring that different test items are tested at a specified height, thereby facilitating different test items and solving the problem that currently, micro-compression fields at home and abroad often adopt an integrated structure, and the types of test items are different.
