Abstract
An apparatus with structures in a conductive film that let a selected set of RF frequency bands pass through, while blocking the passage of all other frequencies is disclosed. The film may include a first portion of the film and a second portion of the film circumscribing the first portion. The second portion is separated from the first portion by a first gap along a periphery of the first portion of the film and wherein a width of the first gap is associated with a wavelength of a first radio signal.
