Rapid teaching experiment antenna E-H surface test conversion device

Abstract

The invention provides a rapid teaching experiment antenna E-H surface test conversion device. The device mainly comprises three main parts including a fixed member, a rotation seat and a positioningpin, wherein the fixed member is used for connecting with an antenna rotary table, the rotation seat is connected with an experiment antenna, and the positioning pin is used for locking and fixing thefixed member and the rotation seat. A rapid teaching experiment antenna E-H surface conversion method is realized. According to the method, through single 90-DEG rotation, after rotation to the rightplace, rapid locking can be carried out through the pin, antenna E-H surface switching is realized, and the switching process requires no other operation and can be completed by a single person within seconds.

Description

technical field [0001] The invention belongs to the technical field of teaching experiment devices, and in particular relates to a fast conversion device for E-H surface testing of teaching experiment antennas. Background technique [0002] In the teaching experiment activities of antenna courses for electronics and information engineering majors in colleges and universities, in order to enhance students' interest in experimental courses and the effect of teaching experiments, deepen students' understanding of basic knowledge of antennas, enable students to learn and master antenna testing techniques, and train students To improve the practical operation ability and engineering application ability, it is necessary to carry out the E-plane and H-plane pattern test experiments of various antennas. At present, most teaching experiment antennas are fixed on the antenna turntable through the adapter, and the experimental antenna, the adapter, and the antenna turntable are not mov...

AI Technical Summary

Problems solved by technology

In addition, the connecting rods for the docking of traditional adapters and antenna turntables are usually polished rods, and the mounting surface and mounting holes for experimental antennas left by traditional adapters are also relatively simple.

[0004] The disadvantages of the prior art mainly include: 1. Due to the different structures of various types of antennas, when carrying out different types of antenna test experiments, when the antenna needs to be replaced, different adapters need to be replaced

2. Due to the fixed structure of the antenna, it is necessary to replace (or increase or decrease) different adapters when carrying out the E-plane and H-plane pattern test experiments of the same antenna

3. The number of adapters increases with the increase of the number of antennas, and the management and identification of adapters become more difficult

4. Whether it is an antenna, an adapter or an antenna turntable, there is a possibility of accelerated damage to the mounting holes after frequent disassembly and assembly.

5. When replacing the adapter, it is usually necessary to adjust the height of the antenna turntable, which further increases unnecessary operations and is inefficient

6. When the antenna is large or heavy, two or even more people are required to cooperate, which is time-consuming and labor-intensive

7. The connecting rod connecting the traditional adapter and the antenna turntable is usually a bare rod. When the connecting rod is inserted into the antenna turntable, the set screw directly pushes against the smooth cylindrical surface of the connecting rod, and there is a risk of unreliable fixation.

When the connecting rod slides up and down due to insecure fixation, the set screw will also scratch the cylindrical surface of the connecting rod

8. The mounting surface and mounting hole for the docking of traditional adapters and experimental antennas are single, resulting in the need for additional adapters to install some experimental antennas
