Abstract
A multiple band antenna has an RF coupling structure () and a resonant RF structure (). The RF coupling structure () has an RF connection () and an RF coupling end (). The resonant RF structure () is reactively coupled to the RF coupling end (). The resonant RF structure () has a first end () and a second end () and has a conductive perimeter () enclosing at least one slot area () configured to induce an additional resonant RF band for the resonant RF structure (). The first end () and the second end () are reactively coupled to a ground plane () to facilitate longer wavelength operation. Cellular phones () and wireless communications sections incorporating such antennas are also provided.
