Abstract
Disclosed are a non-feeding re-radiating repeater and a method for manufacturing the same. The repeater includes: a dielectric substrate having a flat plate shape or a curved shape; and one or more unit cells formed on the dielectric substrate, in which each of the unit cells includes an arrangement of a plurality of conductor patterns. When electromagnetic waves incident from a first direction, the unit cells may re-radiate the electromagnetic waves in a second direction which is different from the first direction.
