摘要
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 x 17 x 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.
