Raghavan  \nDepartment of Electronics and Communication Engineering  \nNational Institute of Technology  \nTrichy  \n[raghavan@nitt.edu](raghavan@nitt.edu)  \nABSTRACT  \nThis study, conducted in 2017, explores the use of Machine learning algorithms to predict Characteristics of Transmission Lines such as Impedance or resonance frequency using design parameters of Transmission Lines. Using formulas and equations that define the characteristics of Transmission lines, training data was generated. We trained different models for this dataset. The extent of deviation of predicted output from the actual output was measured in terms of maximum error and average error. This helped determine how well an algorithm worked for a particular transmission line. Further, the best-suited algorithm for each transmission line under consideration was found based on the error.  \n1  \n1 Introduction  \nMachine learning has significantly advanced the field of microwave research, particularly in the areas of modeling, simulation, and optimization. Notably, the work by Naser-Moghaddasi et al. [5] demonstrated the application of heuristic artificial neural networks to analyze and synthesize the performance characteristics of rectangular microstrip antennas. Their approach highlighted the potential of neural networks to predict antenna behavior effectively, thereby streamlining the design process. Building upon such foundational studies, this paper extends the use of machine learning to model a broader range of transmission line characteristics. Specifically, we expand the application of machine learning models to include various types of transmission lines such as Microstrip, Slotline, Stripline, Co-Planar Waveguide (CPW), Co-Planar Strip (CPS), and Microstrip Patch Antenna, employing both Linear Regression and advanced Neural Networks. In this publication, we explore the results for the Microstrip line and Microstrip patch Antenna.  \nThis research leverages standardized historical data to train models that can predict the electrical properties of planar transmission lines, based on physical dimension parameters. This method simplifies the practical design process, enabling the prediction of output parameters for all combinations of inputs before fabrication. Such predictive modeling saves considerable time and resources in antenna design and simulation efforts. Furthermore, the trained models can be utilized to predict the characteristics of new transmission lines, eliminating the need for extensive empirical simulation. This study aims not only to validate the effectiveness of machine learning models in replicating known transmission line behaviors but also to enhance their accuracy and generalizability compared to earlier works. Thus, this research not  \n1This research was conducted in the year 2017 .  \nonly confirms the utility of machine learning in this domain but also advances its capability to accommodate a wider array of transmission line configurations and complexities.  \n2 Transmission Line Models  \nAccording to a Microstrip design proposed by K.C.Gupta and Ramesh Garg[1]: For w/h > 1  \nϵeff = ϵr~~ ~~+~~ ~~12 + ϵr~~ ~~−2~~ ~~1  ~~ ~~q1~~ ~~12~~  ~~HW~~ ~~   \nZ0 = 2~~ϵ~~0eπff 􀀒 WH + 1 .393 + 23 ln 􀀒 WH + 1 .444􀀓􀀓 Ω  \nA proposed design of Microstrip Patch Antenna by Bablu Kumar Singh[3]:  \n1  \nϵeff = ϵr~~ ~~+~~ ~~12 + ϵr~~ ~~−2~~ ~~1 􀀒 1 + 12 ~~ ~~hW􀀓 − 2 ∆L = 0 .412h 􀀒 ϵϵefeff02.358 􀀒 Wh + 0 .264􀀓􀀓  \nc  \nfr = 2 √ ϵeff (L + 2∆L)  \n2.1 Microstrip Lines  \nMicrostrip is a planar transmission line used to carry Electro-magnetic waves (EM waves) or microwave frequency signals.
