FIELD: physics.
SUBSTANCE: invention relates to antenna technology, in particular to the design of active phased antenna arrays (APAA) and digital antenna arrays (DAA). Ring modular concentric antenna array contains emitters located in several concentric circles, while the radiators are grouped into row-column rectangular sublattices located at different angles with respect to each other with the possibility of changing these angles.
EFFECT: technical result is an improvement in the energy characteristics, a simplified design and an increase in the manufacturability of annular antenna arrays.
