Patent attributes
The present disclosures provide methods and apparatuses for a metamaterial antenna structure having a plurality of super elements of slotted transmission lines. The metamaterial antenna structure has an aperture structure with apertures positioned in a specific orientation relative to a centerline of the aperture structure and configured to propagate transmission signals from a distributed feed network through the apertures. The metamaterial antenna structure also has a transmission array structure comprising a plurality of transmission lines coupled to the aperture structure and configured to propagate the transmission signals from the aperture structure through one or more slots in the transmission array structure, in which the apertures of the aperture structure are interposed between the slots. The metamaterial antenna structure also has a radiating array structure coupled to the transmission array structure and configured to radiate the transmission signals from the transmission array structure.
