A wideband folded monopole antenna coupled with a parasitic inverted-L element for 2.3-10.6-GHz band laptop computer applications is presented. The designed antenna is composed of a printed folded monopole with an asymmetrical line width and a parasitic inverted-L element. The input impedance is matched by widening the line width of the folded monopole and adjusting the space between the parasitic inverted-L element and the folded monopole. The measured -10-dB bandwidth is 4.85:1 (2.27-11-GHz), and the size of the antenna is 13.75 (1-/10) mm-12 (1-/11) mm (where --2.27-GHz).
