A novel ultrawideband (UWB) antenna with a single parasitic U-type element is reported to exhibit dual-band notch peculiarities. A slotted radiator and a novel defected ground structure (DGS) comprise the proposed antenna, which has a bandwidth of 2.9-11.75 GHz (121%) in the UWB spectrum. By etching a single inverted U-shaped parasitic element on top of the DGS, two rejected bands at the downlink of X-band (6.8-8 GHz) and the uplink of X-band (9.7-11.3 GHz) applications are achieved. The proposed antenna is printed on an FR-4 substrate with a compact size of 24 x 28mm2, has a gain fluctuation of 1.4-5.7 dBi, and a peak radiation efficiency of 92.3%. The suggested antenna is a viable candidate for downlink and uplink X-band notched UWB applications owing to the excellent agreement between its measured and simulated results.
