Summary:
A printed L-shaped slot antenna for WWAN metal-rimmed smartphone applications is presented in the paper. Embellished by the metal rim, the modern smartphones have achieved enhanced mechanic strengthen as well as better cosmetic appearance. However, the only problem should be addressed on the resonance disorder introduced by the metal rim. Although it has been partially solved by etching slits and adding grounded patches, yet the metal rim resonances are not fully utilized which results in large size consumption. In the proposed scheme, the resonances generated by the metal rim are better exploited to further reduce the antenna size. Four resonant modes are generated by the disjoint metal rim and double L-shaped slots to cover the WWAN band operation. With small size occupation and wide band coverage, the proposed antenna is a promising candidate for the metal-rimmed smartphone applications.
