Abstract

A film-antenna capable of generating two wide resonant modes for covering the AMPS/GSM bands and the DCS/PCS/ UMTS bands for mobile phones is proposed. The antenna consists of two superimposed radiating arms which can support two resonant modes by themselves. The frequency range of a resonant mode generated by one of the arm is arranged to differ a little with the corresponding mode of the other, at the fundamental and higher-order modes. As a result, the bandwidths at both of the resonant modes are significantly enhanced. The antenna has a dimension of 5times15times40 mm³ and shows fairly good omni-directional radiation patterns at all the operating bands.
