Abstract

A passive radiofrequency device includes a core formed by the gluing of multiple parts in direct contact against one another. At least one of the parts includes a housing for glue. At least some of the parts are manufactured individually by additive manufacturing. A conductive metal jacket surrounds the core without separating the parts from one another.
