In this paper, a compact band-notched UWB planar antenna with Transmission-Line-fed is presented and I'm using a new technique by etching a narrowband resonance H-shape slot in the ground plane of the antenna. This antenna is capable reducing the interference at the WLAN bands by eliminating the 4.85-6.17 GHz band. The proposed antenna has compact size of 16 × 22 mm 2 including the ground plane and because of miniature dimensions, good radiation patterns with monopolar characteristics are
