A novel compact band-notch ultra-wideband (UWB) printed monopole antenna is proposed, where the band notch characteristic is realized by inserting a pair of hook-shaped slit in the both side of radiating patch. Also, by inserting a π-shaped stub in the ground plane, additional resonance is excited and hence the bandwidth is increased up to 123%. This novel monopole antenna has ultrawide impedance bandwidth, compact size, low fabrication cost, and omni-directional H-plane radiation patterns which are suitable for various broadband applications.
