GPS antenna auxiliary debugging system

Abstract

The invention discloses a GPS antenna auxiliary debugging system, which comprises a grinding mechanism, a GPS antenna, a vector network analyzer and a computer, and is characterized in that the vector network analyzer is used for acquiring an S11 parameter of the GPS antenna, and the computer is used for calculating a physical quantity corresponding to the S11 parameter and issuing a tuning position and a tuning quantity to the grinding mechanism; the grinding mechanism is used for grinding the GPS antenna, the surface of the GPS antenna is provided with a radiation surface silver coating, and the processing end of the grinding mechanism is used for grinding the radiation surface silver coating; through the design of the invention, the debugging target S11 can be set, the computer accurately calculates the debugging amount through the calculated linear matrix, and a machine can be guided to carry out debugging, so that the tuning position and the tuning amount corresponding to the current S11 and needing to be carried out can be very accurately obtained, and the defects in the existing operation mode are overcome.

Description

technical field [0001] The invention belongs to the technical field of GPS antennas, and in particular relates to a GPS antenna auxiliary debugging system. Background technique [0002] Due to errors in the manufacturing process of the GPS antenna, such as the size of the silver-plated layer on the radiating surface, the dielectric constant of the dielectric body, etc., there will be deviations in the frequency and echo of the antenna. Fine-tuning is carried out to make the indicators meet the design requirements. Among them, the design specifications not only need to meet the requirements of echo specifications, but also meet the requirements of impedance characteristics, so as to ensure that the radiation pattern of the antenna is correct. [0003] At present, the GPS antenna is mainly debugged by manpower, which requires a long period of training for employees. It is mainly polished by observing the S11 curve, which is carried out based on human experience and feeling. ...

Problems solved by technology

[0003] At present, the GPS antenna is mainly debugged by manpower, which requires a long period of training for employees. It is mainly polished by observing the S11 curve, which is carried out based on human experience and feeling. The ability requirements are very high, so it is very unfavorable for the development of enterprises. Therefore, there is a clear demand for machines to replace labor. The known literature has also proposed a method for automatically modeling RF passive devices using AI algorithms, but The AI ​​method requires a lot of training, the data acquisition efficiency is low, and the requirements for the computer are also high, the cost is relatively high, and the operation is complicated
