Currently, in order to increase the information capacity of wireless data transmission channels, increasingly higher frequencies are being mastered. However, interest in low-frequency channels has not been lost. Possessing a low information capacity, they have significantly lower propagation losses in free space, thereby providing a greater communication range. Significant difficulties in operating equipment using low-frequency communication channels arise due to the overall dimensions of the receiving and transmitting antenna elements of the electrical type. An alternative solution in this case could be the use of magnetic-type antenna elements, the overall dimensions of which at the same gain value are much smaller. Unfortunately, developing such structures, they require calculation and modeling of their electromagnetic parameters using specialized software packages. The presented algorithm for calculating the radiation pattern of an array consisting of magnetic-type antenna elements makes it possible to calculate the shape of the radiation pattern and the magnetic field strength values in the near zone. The calculations necessary to obtain the result do not require a large amount of computer time and allow you to quickly obtain the necessary results, which significantly reduces the development time of radio engineering devices. The reliability of the results obtained using the algorithm is confirmed by their comparison with well-known ones. However, when implementing and using the algorithm, one should remember the existing limitations and assumptions, some of which can be removed by introducing additional calculation steps and some complication of the calculations.
