Optimized Research On Print Quality Of RFID Label Antenna Based On Neural Network Model

Research at home and abroad show that, RFID tag antenna fabricated through conductive ink screen printing process is the most promising approach of minisize, low cost, large-scale application.In this paper, printing labels antenna in the optimal control of the quality of evaluation, the printing parameter optimization settings, the establishment of neural network model, the antenna size and design of the forecast range of issues such as program evaluation studies were all discussed. Some research results have been obtained and the main innovation results are as follows:â‘ Four key criteria of antenna RFID label printing quality were proposed, and quantitative evaluation of the quality of printing mathematical model was established according to these four key criteria. These key criteria and the evaluation model are suitable for analysis and evaluation of print quality of a variety of microelectronic products including RFID tags.â‘¡Both BP and the RBF neural network model based on optimized print quality was established, so that antenna designers can to control the actual conductor ink membrane size under the best quality printing state, and amend all kind of electrical performance indicators of the tag antenna according to the actual size, so that the electrical performance indicators of the tag antenna and print parameters can be optimize synthetically.â‘¢Through the neural network model for simulation of the forecast, a set of printing parameters including the most a appropriate silk screen, scrape print pressure and speed and so on, can be recommended the printing staff, Which replace the traditional methods that repeatedly adjust the screen resolution and printing parameters on machine in the past. The error controllability, high efficiency, low cost and high quality during printing process can all be obtained.In short, the results of this study can help cooperate between electronic experts and print specialists ,and ensure the performance accordance of the design antennas and print antenna.
