Abstract :
A coplanar waveguide (CPW)-fed dual-wideband antenna formed by a triangular monopole and a U-shaped monopole is presented. The antenna can generate two wide bands centered at about 2.5 GHz and 5 GHz to cover all the 2.4/5.2/5.8 GHz WLAN bands and the 2.5/3.5/5.5 WiMAX bands. Furthermore, the antenna has a simple planar structure and occupies a small size of about 28 X 33 mm2, including the finite ground CPW feeding mechanism. Good dipole-like radiation characteristics over the operating bands are obtained.
