  • Multiband or broadband frequency selective surface
    Publication number: 20030142036
    Abstract: A frequency selective surface includes a pattern of electromagnetic material formed on a substrate suspendable over a ground plane for reflecting or transmitting electromagnetic waves at one or more particular frequencies. The frequency selective surface may include one or more meandering line inductors and/or one or more interdigitated capacitors formed within the pattern of electromagnetic materials for adjusting the frequencies at which the electromagnetic waves are reflected or transmitted. The frequency selective surface may also or instead include one or more inductors and/or one or more capacitors arranged in series within the pattern of electromagnetic materials to adjust the frequencies at which the electromagnetic waves are reflected or transmitted. In addition, the pattern of electromagnetic materials may be formed within the substrate in such a manner that the frequencies at which the electromagnetic waves are reflected or transmitted are tunable.
