In this paper, a low profile printed antenna with dual-band operation for wireless localarea network (WLAN) applications is presented. It provides two separate impedance bandwidths of0.49GHz (2.3-2.79GHz) and 2.22GHz (4.92-7.14GHz). The proposed microstrip-fed antennaconsists of two arc-shaped strips with a nipped stub and a defected ground plane. The proposedantenna occupies a small size (40mm×25mm×1.59mm) and is fabricated and measured. Good omnidirectionalradiation patterns and enough gains across the operation bands are obtained. Thesimulated results are in good agreement with the measured. The effects of the key structureparameters on the antenna performances are also analyzed and presented.
