Abstract

The invention relates to a universal antenna flange plate; the universal antenna flange plate comprises a plate body with a central camshaft; the outer circumference of the plate body extends and is provided with at least one antenna interface board; an obtuse angle structure is formed between the plane where the antenna interface board is arranged and the plane of the plate body; an antenna polarization axis of each antenna interface board intersects with the central axis of the plate body at the same focal point; the outer circumference of the central camshaft of the plat body is provided with a positioning hole with respect to each antenna interface board; the center of the positioning hole is arranged on the projection line of the antenna polarization axis of the corresponding antenna interface board projected on the plate body; a universal antenna switching device comprises the universal antenna flange plate and a scanning frame; the flange plate is rotatably connected on a bevel surface of the scanning frame. The universal antenna flange plate and antenna switching device having the same solve the problem of conveniently switching antennas of multiple tested probes in compact range dead zone test, meanwhile, increase the working efficiency and reliability of dead 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...
