Time of impedance matching of an antenna-feeder path when using of the switched antenna tuner on a straight line depends on the number of switchings of elements of the matching network at working off of an algorithm of tune. In this regard it is important to reduce the number of switchings of relays to a minimum which is reached, for example, when using calculation algorithms. However it can lead to deterioration in coherence of a path after end works of an matching algorithm in view of work of calculation algorithms with idealized analogs of real elements of the matching network circuit. For this reason the question of development of the algorithm providing the minimum quantity of iterations and considering parameters of real elements of a circuit at the moment is extremely relevant.

The aim of the article is to analysis of efficiency of use of neural networks for matching of an antenna-feeder path as a part of the switching antenna tuner device.

The article provides the application of an algorithm of matching of an antenna-feeder path on the basis of the trained neural network with direct link. Estimate efficiency of the using of neural networks for the matching antenna-feeder path as a part of the switching antenna-matching device on the basis of the data obtained from dynamic model of an antenna-feeder path are considered. Numerical results of test of the algorithm of matching of an antenna-feeder path with application of neural network on the example of data of the received from real HF antennas are presented.

The presented results can be used in development of antenna tuner device.
