Abstract

A metalized plastic antenna includes a plastic antenna body with metallization on the inside. In this arrangement metallization is used for conducting electromagnetic waves. Furthermore, metallization may be implemented as a protective coating so that chemical resistance of the plastic antenna may be ensured even in the case of corrosive environmental conditions.
