ANTENNA DOME Russian patent published in 2021 - IPC H01Q1/42 

FIELD: antennas.

SUBSTANCE: invention relates to antenna equipment, particularly to antenna domes of high-speed missiles with casings made of heat-resistant ceramic materials. The technical result is achieved based on the fact that in the antenna dome containing a radiotransparent casing, comprised of an external ceramic heat-protective element and an internal power radiotransparent element, and a metal frame, interconnected with a heat-resistant adhesive, in contrast to the prototype, the internal power radiotransparent element of the casing is made of heat-resistant fiberglass with dielectric permeability close or equal to the dielectric permeability of the external heat-protective element and integral emission coefficent of ε ≤ 0.6, and is connected to the external element of the casing by a heat-resistant adhesive or moulded onto it, wherein the total thickness of the external and the internal elements is equal to the electrical thickness of the casing wall, the thickness of the internal element in the radiotransparent area does not exceed 30% of the electrical thickness of the casing wall, and in the transition area between the radiotransparent area and the connection unit and in the connection unit of the casing and the frame the thickness is calculated based on the condition of achieving a minimum stress in the external ceramic element given simultaneous impact of an external power load and thermal thrust by the frame.

EFFECT: technical result of the invention is provided performance ability of the antenna dome under conditions of significant heat and power impact on the radiotransparent casing.
