1. A method for tuning a resonant frequency of a Composite Right/Left Handed (CRLH) Metamaterial (MTM) antenna device, comprising:

  • providing a CRLH MTM antenna on a substrate, the CRLH MTM antenna comprising antenna elements that are structured and electromagnetically coupled to one another to form a CRLH MTM structure;

    providing a plurality of electrically conductive tuning elements on the substrate that are separated from one another and from the CRLH MTM antenna; and

    selecting one or more electrically conductive tuning elements located next to respective antenna elements to connect the selected one or more electrically conductive tuning elements to at least one of the respective antenna elements to make the selected one or more electrically conductive tuning elements as part of the CRLH MTM antenna to tune a resonant frequency of the CRLH MTM antenna to be different from an initial value of the resonant frequency when the selected one or more electrically conductive tuning elements are not connected.
