Abstract
The invention relates to walls that are used for constructing radomes, in particular radomes for aircraft radars, as well as radomes using such walls. According to the invention, the inner and outer layers of said wall are separated by a central core including a central portion made of dielectric material flanked by two lateral portions made of the same dielectric material but with a recess, the aggregate of said portions being obtained by juxtaposition of elemental dominoes.
Claims18
A wall for a radome, comprising:
- two end layers of dielectric material;
- a plurality of unit elements of dielectric material arranged between said two end layers for forming a central core, each of said unit elements comprising a central portion having two main sides which are parallelograms connected by lateral sides, said central portion made of a first dielectric material having a first equivalent dielectric constant that is substantially equal to that of said dielectric material of said end layers, and two lateral portions arranged on each main side of said central portion between said central portion and said end layers, respectively, and made of a second dielectric material having a second equivalent dielectric constant that is low compared to that of said dielectric material of said end layers.
