This paper presents an analysis of topology and parameters of neural network for simulation reflection coefficient and gain of wideband tapered slot antenna.

Simulation results. Neural model of tapered slot antenna was created. This model contains 40 neural networks for simulation reflection coefficient and gain of tapered slot antenna in frequency range 3,1 10,6 GHz.

Conclusions. The optimal parameters were found. Optimal training function is Levenberg-Marquardt backpropagation. Optimal activation function is hyperbolic tangent. Optimal topology of neural network for simulation reflection coefficient and gain of tapered slot antenna is 1020101. These optimal parameters provide an average error of 0,023 for reflection coefficient and 0.163 for gain.

Keywords: antenna, antenna parameters, optimal neural network, Vivaldi antenna
