A compact CPW‐fed dual‐wideband antenna formed by a rectangular ring monopole and a rectangular monopole is presented. The measured 10 dB bandwidths for return loss are achieved to be 46.3% (2.36–3.78 GHz) and 31.4% (5.1–7 GHz) in the lower and upper band, respectively, covering all the 2.4/5.2/5.8 GHz WLAN bands and the 2.5/3.5/5.5 GHz WiMAX bands. Further, the proposed antenna has a simple planar structure and occupies a small size of 28 × 36 mm 2 , including the finite ground CPW feeding mechanism. Good monopole‐like radiation characteristic are obtained over the operating bands. © 2010 Wiley Periodicals, Inc.
