Abstract
A meta-material filter that may be used in constructing a duplex filter is provided. The metal-material filter is comprised of a substrate, a plurality of metal strips periodically positioned on the substrate, and a ground plane spaced from the plurality of metal strips. The plurality of metal strips may be arranged mono-periodically or bi-periodically.
Claims21
A meta-material filter, comprising:
- a substrate;
- a plurality of metal strips periodically positioned on the substrate, wherein the plurality of metal strips comprise at least first and second size strips arranged in a mono-periodic pattern wherein each of the plurality of metal strips is separated by a slot;
- and
- a ground plane spaced from the plurality of metal strips.
1 more element
A meta-material filter for filtering radiofrequency (RF) signals in a band centered on a center frequency that is associated with a characteristic wavelength, comprising:
- a substrate;
- a plurality of metal strips periodically positioned on the substrate, each of the plurality metal strip has a characteristic dimension that is less than or equal to 1/10 of the characteristic wavelength;
- and a ground plane spaced from the plurality of metal strips.
