Patent ID: 8704730

Claim:
An antenna device comprising: a substrate structure comprising one or more metallization layers structured to include: a first ground electrode which is formed in one of the one or more metallization layers; and a plurality of electrically conductive parts formed in at least one of the one or more metallization layers for transmitting and receiving an antenna signal, the plurality of conductive parts including: a cell patch; a feed structure coupled to the cell patch using a capacitive coupling; and one or more connecting units, each mechanically engaging parts of the substrate structure and electrically coupling the first ground electrode to a second ground electrode comprising an assembly separate from the substrate comprising the one or more metallization layers; wherein the plurality of electrically conductive parts and at least part of the substrate structure are configured to form a composite left and right handed (CRLH) antenna structure that exhibits a plurality of frequency resonances associated with the antenna signal.
