An approach for increasing the gain of an antenna array based on Fabry-Perot cavities with mechanoelectrical scanning in the 60-90o angle sector by using a radio-absorbing material on the shading subarray is described. Simulation and analysis of the directional characteristics of the antenna array based on Fabry-Perot cavities with a radio-absorbing material have been performed, and the characteristics have been compared with those of the antenna array without an absorber. Conclusions on the applicability of the proposed configuration of the antenna array based on Fabry-Perot cavities in mobile satellite terminals are made. Keywords: antenna array, Fabry-Perot cavity, wide-angle scanning, radio absorber.
