Abstract :
A novel band-notched ultrawideband monopole antenna is presented. The proposed antenna consists of a stepped square radiating patch, two rod-shaped parasitic structures for generating band-notched function instead of changing the patch or feeding shapes, and a notched ground plane with two novel V-shaped slots that provide a wide usable bandwidth of more than 200% (3-22.5 GHz). With two rod-shaped parasitic structures, frequency band-stop performance is generated, and characteristics such as band-notch frequency and bandwidth can be controlled. The designed antenna has a small size of 12 × 18 mm2 while showing the band-rejection performance in the frequency band of 5.1/5.9 GHz. The bandwidth of proposed antenna is wider than the bandwidth of antenna in the references.
