New Based GPR Model For FGCPW Coplanar Waveguide Analysis

In this work, we propose a new model using the machine learning method GPR to modelling the electromagnetic behaviour of a transmission line coplanar with finite ground FGCPW. This model is based on the relative permittivity the substrate and the geometrical dimensions of the line. The database was created by the use of a high-frequency simulator and for a multi-dimensional transmission line with several lossless materials whose relative permittivity varied between 2,1 and 9,2. The method of the S-parameters is exploited to find the effective permittivity; in addition, this parameter is defined as an output in our model. The results obtained show that our model is efficient to translate this electromagnetic behaviour by comparing with the CMT technique, and which show the criterion of the chosen method.
