Abstract :
A CPW-fed compact printed monopole antenna is proposed for portable UWB devices. The semi-ellipse and rectangle structure are combined as the radiator to expand the bandwidths of antenna to 2.3~20.1 GHz (VSWR<;2), except for the two sub-bands of 3.1~4.4 GHz for WiMAX (3.3~3.7 GHz), the C-band satellite communication systems (3.7~4.2 GHz), and 5.1 ~5.9 GHz for WLAN. These notched sub-bands are obtained by etching two C-shaped (circular arc) slots on the radiating patch. The measured results are in good agreement with the simulated ones.
