Sammanfattning
A novel ultrawideband square antenna with dual bandnotched 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 21 317 31 mm3, 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.
