ANTENNA DOME Russian patent published in 2014 - IPC H01Q1/42 

FIELD: radio engineering, communication.

SUBSTANCE: antenna dome comprises a ceramic cladding, a metal attachment ring and, placed coaxially in the inner cavity, a dome-shaped radioparent heat shield joined to the cladding by a heat-resistant adhesive on the entire surface adjoining to the cladding. The shield is made of heat-resistant fibre glass based on organosilicon, polyimide or phenol-formaldehyde binder and quartz glass fabric with sateen or volume weave. The external and internal surface of the shield is coated with a heat-resistant coating of organosilicon or fluoroplastic enamel. In the inner cavity of the shield there is a metal ring which is joined to the shield by a heat-resistant adhesive and to the attachment ring through the shield by fastening elements in the form pins or screws.

EFFECT: reduced heat exposure of antenna devices of homing heads and the external ceramic cladding of the antenna dome in non-steady high-temperature conditions.
