This article presents the compact planar antenna with 3.5/5.5/8.2 GHz triple band-notched characteristics. The antenna consists of an octagon shape patch with 50 Omega transmission line. By etching two C-shaped slots in the patch and adding pair of L-shaped resonator coupled to the radiating patch, band-rejected filtering properties in the WiMAX/WLAN/ITU bands are achieved. The proposed ultrawide band (UWB) antenna is optimized to operate in the frequency band from 3 to 11 GHz for VSWR < 2. Measured results confirm that the antenna is suitable for UWB applications because of its compact size and high performance.
