Abstract
A wireless device including at least one parallel resonance element and a plurality of serial resonance components is provided. The at least one parallel resonance element may be configured to radiate in at least one frequency. The plurality of serial resonance components may be configured to radiate in a plurality of frequencies. The device may further include a distributed feed element configured to couple to the parallel resonance element and the serial resonance components and serve as a radiofrequency signal feed.
