Abstract
A method of changing a resonant frequency of an antenna includes coupling the antenna to a ground plane of a circuit board, where the ground plane includes conductive material. The method further includes removing a section of conductive material from a first location of the ground plane, where the shape of the removed section and the first location determine the resonant frequency of the antenna.
