RADAR ANTENNA ARRAY Russian patent published in 2011 - IPC H01Q21/00 

FIELD: radio engineering.

SUBSTANCE: radar antenna array includes set of antenna modules installed in housing (3), which is equipped with base to be combined with suspension assembly (4); housing (3) of antenna array is tight and combined with fairing of antenna modules, which is made in the form of protective electromagnetic transparent wall of housing (3) of antenna array. Longitudinal frame element is hollow and is made in the form of stiffeners fixed in slots of antenna array base with antenna modules enveloping their walls; at that, they are made as an integral part, thus forming stiff construction with external hollow wall of housing (3) of antenna array, in which there made are inlet holes for forced air supply with external ventilation devices; at that, stiffeners form together with external wall of housing (3) of antenna array the channels for passage of air flow, and which are isolated from inner volume of antenna array.

EFFECT: reducing metal consumption at simultaneous improvement of thermal mode of antenna modules and secondary power supplies.
