Abstract
	The article describes a method for implementing an antenna array for a Doppler velocity and drift angle meter, which is determined by the features of the flight mode of the aircraft, its performance characteristics and the parameters of the underlying surface. Patch antennas are used to create the required parameters. This article presents the results of modeling a patch antenna for a helicopter DVS in CAD CST, then, to ensure the deviation of the beams of the DP from the perpendicular to the surface of the antenna fabric at the given angles, a feed line with phase delay loops was modeled, and in order to align and increase the overall level gain applied shielding layers. Using the vector network analyzer R&S ZNA, the antenna matching levels with a 50 Ohm path were measured, the standing wave ratio (SWR) at the antenna input does not exceed 1.1. To evaluate the gain, the final topology was simulated, which amounted to more than 29 dB. According to the results of the work done, it was found that the optimized geometric dimensions of the antenna, and the data obtained during the simulation, were confirmed by the results of experiments. Thus, this topology can be used to implement antennas of this type.
