The radiator is typically in the form of a patch array radiator or a slot array radiator.

The wearing portion 150 may be made of metal or plastic, and the wearing portion 150 may be made of any material according to actual requirements. The wavelength range corresponding to the millimeter wave is 1 mm-10 mm.
