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 sub-band of 3.1~4.4 GHz for WiMAX (3.3~3.7 GHz) and the C-band satellite communication systems (3.7~4.2 GHz). The notched sub-band is obtained by etching a C-shaped (circular arc) slot on the radiating patch. The measured results are in good agreement with the simulated ones.
