This paper presents a new band-notched ultrawideband (UWB) planar monopole antenna, consisting of a feed microstrip line, a U-shaped radiator, and a pair of open-loop ring resonators. By properly adjusting the circumferences of the open-loop ring resonators, the notched band of the proposed antenna can be controlled as anticipated.
