Patent ID: 6992640

Claim:
A radome comprising: a first skin portion having opposed first and second surfaces; a first core portion on the first surface of the first skin portion, the first core portion having opposed first and second surfaces, the first surface of the first core portion facing the first skin portion; a high relative-dielectric-constant layer on the second surface of the first core portion, the high relative-dielectric-constant material layer having opposite first and second surfaces, the first surface of the high dielectric-constant-layer facing the first core portion; a second core portion on the second surface of the high relative-dielectric-constant layer, the second core portion having opposed first and second surfaces, the first surface facing the high relative-dielectric-constant layer; and a second skin portion on the second surface of the second core portion, wherein the high relative-dielectric-constant layer has a relative dielectric constant that is larger than the relative dielectric constants of the first and second skin portions and the first and second core portions.
