Keywords:compensation method, mutual coupling, cellular phone antenna, dark spot, electromagnetic fields
AbstractIntroduction. The paper proposed a method of reducing irradiation human head by cellular phone antenna. A method of solving this problem, called the compensation method. In this method, an additional radiator is placed between the head and handset (main) radiator.
The results. In this work were found the electromagnetic fields. Also we solved system of linier equation and calculated the currents of radiators. We found the boundary surface of the dark spot.
Conclusion. We have described the characteristics of the compensation method for the creation of weak-field area in the near region of transmitting antenna. The dimensions of the weak-field area were determined, And the mutual coupling between the main and auxiliary antennas was analyzed. The results obtained showed that under realistic condition, the compensation method permits decreasing the irradiation power by a factor of 4 to 50. Methods of wideband field compensation will be separately considered.
