Coplanar antenna

摘要

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.
