1. A method of changing a resonant frequency of an antenna, comprising:

  • coupling the antenna to a ground plane of a circuit board, where the ground plane comprises a conductive material; and

    removing or omitting a section of conductive material in a first shape from a first location of the ground plane, where the first shape and the first location determine the resonant frequency of the antenna and where removing or omitting the section of conductive material in the first shape produces a cut in the ground plane;

    connecting a first circuit component to a first side of the cut in the ground plane and to a second side of the cut in the ground plane at a first position relative to the cut; and

    connecting a second circuit component to the first side of the cut in the ground plane and to the second side of the cut in the ground plane at a second position relative to the cut that is different than the first position.
