radome

(ray -dohm) A protective covering over a radio antenna that is transparent to radio waves at the frequency in use.

radome

[′rā‚dōm]
(electromagnetism)
A strong, thin shell, made from a dielectric material that is transparent to radio-frequency radiation, and used to house a radar antenna, or a space communications antenna of similar structure.

Such materials can be used to build antenna radomes with improved transparency and even with new features such as the property of being tunable or switchable, thus resulting in a new class of devices: metamaterial radomes or "metaradomes" [2, 3].
An antenna radome of 3 mm thick fabricated by ABS medium (relative permittivity [[epsilon].sub.r] = 2.8, tan [delta] = 0.01) is used to cover the whole antenna in order to protect the antenna from damage.

Color is not something that would immediately come to mind when considering antennas, but RFS receives requests for advice about refinishing weathered antenna radomes or changing the radome color for aesthetic or non-aesthetic reasons such as camouflage.
Design engineers developing stealth coatings, antenna radomes and microwave absorbers can characterize materials employed for these purposes by using the 2300-11A materials measurement package.
