A kind of screen door of concentric conical tem room

Abstract

The embodiment of the invention provides a concentric conical TEM (transverse electromagnetic mode) chamber screen door. A screen door cover is inserted into a screen door frame to form the screen door, the cambered surface of a screen door core of the screen door cover is consistent with the cambered surface of the inner wall of a cavity of an open window part of a concentric conical TEM chamber, so that after the concentric conical TEM chamber screen door is mounted in the concentric conical TEM chamber, the screen door cannot form a bulge or a concave in the concentric conical TEM chamber, and interference of the screen door with a magnetic field in the concentric conical TEM chamber is reduced. Moreover, the screen door core in the concentric conical TEM chamber screen door can be used for mounting a field intensity probe, therefore, the problems that space in the cavity of the concentric conical TEM chamber is small, a field intensity probe cannot be mounted on a traditional TEM chamber screen door, and space in the concentric conical TEM chamber is wasted can be further solved. Through the two points, the concentric conical TEM chamber screen door is more suitable for the concentric conical TEM chamber.

Description

technical field [0001] The application relates to the field of radio measurement, in particular to a screen door of a concentric conical TEM chamber. Background technique [0002] In the field of radio measurement, since field strength is one of the basic parameters of radio, the measurement accuracy of field strength is very important in the field of radio measurement. In order to enable the field strength probe to accurately measure the field strength, it is generally necessary to calibrate the field strength probe before measurement or delivery, so the calibration accuracy of the field strength probe will directly affect the calibration result of the field strength probe, thereby affecting Measurement accuracy of field strength probes. [0003] Generally, when the field strength of different frequency bands is calibrated, the Transverse Electromagnetic Mode (TEM) room method, the Gigahertz Transverse Electromagnetic Mode (GTEM) room method, and the standard field method ...

AI Technical Summary

Problems solved by technology

[0006] The embodiment of the present invention provides a concentric conical TEM chamber screen door, which is used to solve the problem that when the concentric conical TEM chamber uses the traditional TEM chamber shield door in the prior art, the traditional TEM chamber shield door has a large interference to the electromagnetic field and cannot The installation of field strength probes causes the problem that the traditional TEM room screen door is not suitable for the concentric conical TEM room screen door
