| Abstract | ||||
| This paper presents a design of a compact and simple ultra-wide band planar antenna with dual band notched. The antenna consists of a microstrip-fed line and two rectangular slots in the ground plane. The design produces a wide band operation with return loss less than -10dB in the frequency range of 2 to 9.5 GHz. By using a rectangular patch in conjunction with a U patch and etching a U-shaped slot in the feed line, the band of the antenna is increased with two notched bands of central frequencies at 3.5GHz and 5.5 GHz. Defected ground plane and an open shunt stub are proposed to improve the impedance bandwidth of the presented antenna. Parametric studies of antenna elements are presented. The proposed antenna is fabricated. The measured data show very good agreement with the simulated results. | ||||
