ANTENNA ARRAY Russian patent published in 2024 - IPC H01Q9/04 

FIELD: antenna equipment.

SUBSTANCE: invention relates to antenna arrays and serves as an antenna for a satellite navigation receiver. Result is achieved by the fact that the proposed antenna array contains N+1 elementary radiators, which are located on the surface of the metal screen according to the "star" scheme, including one central elementary radiator and N peripheral elementary radiators, as well as a signal processing unit, which is connected to the outputs of the elementary radiators, characterized by that a calibration system is introduced into the antenna array, which consists of N pin radiators and the power supply circuit of the pin radiators, pin radiators are located on the surface of the metal screen perpendicular to its plane, along the circular line with the center coinciding with the center of the antenna array, power supply system of pin radiators is made in the form of a power divider, which contains a central port and N peripheral ports, the central port of the power divider is connected to the signal processing unit, and peripheral ports of power divider are connected to inputs of pin radiators.

EFFECT: increase in the level of suppression of spurious signals by up to 10 dB and increase in the accuracy of determining coordinates when equipping satellite navigation systems.
