A compact multi-broadband planar antenna is proposed for wireless handsets. The proposed antenna covers multiple broad frequency bands, including the 900-MHz band with a bandwidth of 29% (790-1061 MHz), the 2-GHz band with a bandwidth of 51% (1650-2775 MHz), and the 3.5/5-GHz band with a bandwidth of 68% (3132-6382 MHz). The multi-broadband antenna consists of a folded monopole coupling to an S-shaped strip for the 900-MHz band, a C-shaped monopole coupling with a C-shaped strip for the 2-GHz band, and a trapezoidal monopole with an inverted-F monopole for the 3.5/5-GHz band. All these monopoles with coupled strips are printed on a planar substrate with a compact size of 15 mm×60 mm×0.5 mm, suitable for emerging ultra-slim GSM/UMTS/LTE and WLAN/WiMAX handsets.
