A novel ultrawideband square antenna with dual band‐notched performances is proposed. To obtain extended impedance bandwidth, novel techniques on the ground plane are used. Besides, the stopbands are realized by a I‐shaped defected ground structure as well as a L‐shaped arm ended up shorting pin on the top of the back plane. The experimental results exhibit that the antenna, with compact size 21 × 17 × 1 mm 3 , has an impedance bandwidth of 2.6–11.8 GHz for voltage standing wave ratio less than 2, except two frequency stopbands of 3.2–3.7, 5.1–5.9 GHz. © 2013 Wiley Periodicals, Inc.
