In a particular embodiment of the present disclosure, a coplanar antenna includes a conductive plane having a first dimension and a second dimension, wherein the length of the conductive plane along the first dimension is less than one-quarter of a wavelength of a resonant frequency； an insulating region disposed within the conductive plane, wherein the insulating region is of a shape that outlines a conductive peninsula, wherein: the conductive peninsula is coupled to the conductive plane； the conductive peninsula is substantially coplanar to a major portion of the conductive plane； the conductive peninsula is electrically coupled to an electric feed circuit such that an impedance associated with the conductive peninsula when electrically coupled substantially matches a signal impedance at the electrical feed circuit； and the conductive peninsula is operable to resonate at the resonant frequency after receiving a current from the electric feed circuit.
