Embodiment 1

[0051] Such as figure 1 As shown, a carrier provided by an embodiment of the present invention has a shuttle-like structure in which the left end 10 and the right end 20 are pointed;

[0052] The top of the carrier is provided with an antenna installation groove 30, and the distance between the installation groove 30 and the left end 10 and the right end 20 is equal;

[0053] The antenna under test can be installed in the installation slot 30 , and the left side of the antenna under test is opposite to the left end 10 , and the right side of the antenna under test is opposite to the right end 20 .

[0054]When in use, the antenna to be tested can be installed in the mounting groove of the carrier so that the left side of the antenna to be tested is opposite to the left end of the carrier, and the right side of the antenna to be tested is opposite to the right end. The antenna installed on the carrier laterally transmits test signals to test the lateral radar cross-sectional a...

Embodiment 2

[0056] Such as figure 2 As shown, the second embodiment is basically the same as the first embodiment, and the similarities will not be repeated. The difference lies in:

[0057] The bottom view of the carrier is rhombus-like;

[0058] Both the upper corner 40 and the lower corner 50 of the rhombus are rounded.

[0059] In the second embodiment, the shape of the carrier is a shuttle-like structure with sharp corners at the left end and the right end, and the bottom view of the carrier is a rhombus-like shape, and the upper and lower corners of the rhombus-like shape are rounded, so when When the test signal is sent from the left or right side of the carrier to the antenna under test, the equivalent signal receiving area of ​​the carrier relative to the test signal is relatively small, further reducing the interference caused by the scattering field of the carrier itself to the scattering field of the antenna under test.

Embodiment 3

[0061] The third embodiment is basically the same as the second embodiment, and the similarities will not be repeated. The difference is that the carrier has a symmetrical structure with a designated dividing plane, wherein the designated dividing plane is perpendicular to the left end 10 and the The connecting line between the right end portions 20, and the center of the carrier is located on the dividing plane. In this way, it can be ensured that no matter whether the test signal is sent from the left side or the right side of the carrier to the antenna mounted on the carrier to test the lateral radar cross-sectional area of ​​the antenna to be tested, the test effect and test result are the same.

Abstract

The invention relates to a carrier, and the carrier is shaped like a fusiform-like structure where a left end part and a right end part are pointed. The top of the carrier is provided with an installation groove for installing an antenna, and the distances between the installation groove and the left and right end parts are equal. A to-be-detected antenna can be installed in the installation groove, wherein the left side surface of the to-be-detected antenna is opposite to the left end part, and the right side surface of the to-be-detected antenna is opposite to the right end part. According to the technical scheme provided by the invention, a test signal is transmitted to the antenna installed on the carrier from the left side or right side of the carrier, so as to more accurately measurethe lateral radar scattering cross section area of the antenna during the testing of the lateral radar scattering cross section area of the antenna.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a carrier. Background technique [0002] When measuring the radar scattering characteristics of an antenna, it is usually necessary to configure a corresponding low-scattering carrier for the antenna. [0003] At present, the existing low-scattering carrier is usually designed for the head-to-head test index of the antenna. When the antenna to be tested is installed on the existing low-scattering carrier to test the antenna's side radar The scattering field of the low-scattering carrier itself will have a great impact on the scattering field of the antenna under test, and it is impossible to accurately measure the lateral radar cross-sectional area of ​​the antenna. [0004] Therefore, in view of the above deficiencies, it is necessary to provide a solution to the problem that the lateral radar cross-sectional area of ​​the antenna cannot be accurately measured. ...
