A multiple band antenna has an RF coupling structure ( 110 ) and a resonant RF structure ( 102 ). The RF coupling structure ( 110 ) has an RF connection ( 116, 118 ) and an RF coupling end ( 112, 114 ). The resonant RF structure ( 102 ) is reactively coupled to the RF coupling end ( 112, 114 ). The resonant RF structure ( 102 ) has a first end ( 106 ) and a second end ( 108 ) and has a conductive perimeter ( 102 ) enclosing at least one slot area ( 104 ) configured to induce an additional resonant RF band for the resonant RF structure ( 102 ). The first end ( 106 ) and the second end ( 108 ) are reactively coupled to a ground plane ( 124, 120 ) to facilitate longer wavelength operation. Cellular phones ( 800 ) and wireless communications sections incorporating such antennas are also provided.
