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

FIELD: radio engineering.

SUBSTANCE: antenna dome includes a radiotransparent ceramic cover; at that, ceramic cover has wall thickness that is by 0.01-0.03 mm less than design dielectric thickness, and its inner surface is provided with polymer coating from methylphenyl spirosiloxane with filler from the cover material in quantity of 40 to 80% with thickness of 0.01 to 0.50 mm. The coating can be made both along the whole inner surface of the cover, and locally. Designing of antenna dome as per the proposed decision allows sufficiently improving radio technical characteristics of antenna dome with radiotransparent ceramic cover; at that, process time of the cover processing on turning machines is rather reduced.

EFFECT: improvement of radio technical characteristics of ceramic antenna domes and reduction of the machining time of ceramic covers on machines.
