Summary:This paper presents the design of a compact UWB antenna with dual band-notch characteristics in the 5 GHz band and X-band satellite communications. The proposed antenna consists of a tapered antenna fed by a microstip feed-line presenting a modified ground plane to achieve a wide impedance bandwidth, in the interval 2.8-12 GHz, with VSWR<2. The electromagnetic coupling of the tapered patch with the rectangular split ring resonator shaped parasitic conductor placed in the ground plane yields the first frequency notch which ranges from 5.05 to 5.95 GHz, in order to eliminate the dedicated short-range communications and wireless local area network interferences. The rejection of the X-band from 7.25 to 8.4 GHz, is achieved by etching a single rectangular split ring resonator slot in the radiator patch. Prototypes of the proposed antenna design were measured and compared to simulations, and good agreement was obtained.
