Abstract: A method and apparatus for changing the electrical characteristics of an antenna in a communications system includes first and second conductive portions separated by a slot. Circuit elements are coupled between the first and second conductive portions, the circuit elements being operably controlled by a bias current to control flow of RF current within the first and second conductive elements, wherein the path of the RF current is directed to be in substantially different locations within the first and second conductive elements.
