Summary: This paper proposes a dual-wideband planar dipole antenna for WLAN and WiMAX applications. The antenna consists of a U-shaped dipole fed by a parallel double transmission line. The U-shaped dipole generates a wide lower band and a narrow higher band. To expand the higher band, two pairs of strips are symmetrically embedded in the U-shaped arms of the dipole. Test results demonstrate that the antenna achieves two wide bandwidths, approximately 53.6% (2.33-4.02 GHz) and 23.7% (5.04-6.45 GHz), in the higher and lower frequency bands, respectively, satisfying the requirements of the entire 2.4/5.2/5.8-GHz WLAN and 2.5/3.5/5.5-GHz WiMAX bands.
