ANTENNA DOME Russian patent published in 2013 - IPC H01Q1/42 

FIELD: radio engineering, communication.

SUBSTANCE: antenna dome consists of a ceramic cover and a metal attachment ring joined to each other by a heat-resistant adhesive. Bending stiffness of the inner flange of the ring is 85-95% of the bending stiffness of the cover in the cross-section passing through the front edge of the ring. The length of the adhesive joint is defined at maximum force action and the radial gap between the cover and the ring is equal to the maximum radial expansion of the ring due to thermal action on the dome. The end gap between the cover and the ring is taken as proportional to the radial gap, with the proportion factor equal to the ratio of the length of the adhesive joint to the outer diameter of the ring, taking into account Young's modulus of the adhesive.

EFFECT: enabling operation of the antenna dome for conditions of simultaneously satisfying the action of prevailing loads.
