A compact microstrip-line-fed antenna designed by inserting two pairs of strips into a rectangular slot for achieving triple-band operation is proposed. The antenna, which occupies a small size of only 40×32×1.6 mm3, utilizes inserted strips to generate dual band-notched characteristics so that three operating bands are able to be achieved, which range from 2.2 to 2.7, 3.07 to 3.86, and 5.13 to 6.23 GHz, sufficiently covering both the 2.4/5.2/5.8 GHz WLAN and 2.5/3.5/5.5 GHz WiMAX bands. In addition, the measured results show good monopole-like radiation patterns and stable antenna gains across the three operating bands.
