Abstract

The radome performance is evaluated by means of a computer aided design (CAD) for the wall structure of multilayer ceramic radome in accordance with the microwave propagation theory. The calculation model for the ceramic radome with A-sandwich structure is built. By optimizing the thickness of the whole wall and the thickness and dielectric constant of skins and core layer, the power transmission efficiency at a broadband frequency of A-sandwich structure ceramic radome is calculated especially. The calculation results suggest that when the wall thickness is 6 mm, the thickness ratio of surface layer to core layer is 1:15 and dielectric constant of core layer is less than 2.5, the maximal broadband transmission efficiency is obtained.
