    Compact UWB monopole antenna with WiMAX/ITU band notch characteristics
    (IEEE, 2017) Guichi, Fella; Challal, Mouloud
    A compact ultra wideband (UWB) antenna with dual band-notched characteristics is proposed and investigated in this article. The antenna is composed of a V-shaped patch with a stair case defect fed by a 50 Ohm microstrip line and a semicircular defected ground plane printed, respectively, on the top and bottom layer of the substrate. The dual band-notch function at WiMAX (3.17-3.85 GHz) and ITU (7.9-9.1GHz) bands are achieved using two parasitic stubs that are attached to the patch, and an inverted U-shaped slot that is etched on the transmission line, respectively. The proposed structure is printed on FR4 material and operates over the frequency range between 2.57-11.3 GHz with WiMAX and ITU dual notched bands characteristics. The measured results of the proposed antenna with overall size of 23×32 mm 2 show acceptable performance and good agreement with the simulated results

    A novel dual band-notch ultrawideband monopole antenna using parasitic stubs and slot
    (wiley, 2017) Guichi, Fella; Challal, Mouloud; Denidni, T. A.
    This paper presents a novel ultra-wideband (UWB) monopole antenna with dual band-notch characteristics. The proposed antenna consists of a V-shaped patch with a stair case defect fed by a 50 X transmission line and a semicircular defected ground plane. It is designed for rejection of dual frequency bands, that is, WiMAX (3.17– 3.85 GHz) and ITU (7.9–9.1 GHz). The 2 bands are achieved by using 2 parasitic stubs that are inserted on the patch, and an inverted U-shaped slot that is etched on the transmission line, respectively. The antenna has a nearly omnidirectional radiation pattern with an acceptable gain across the operating frequency band. A good agreement between the simulated and measured results indicates that the proposed UWB antenna design with overall size of 23 3 32 mm2 is suitable for WiMAX/ITU dual band-notch applications
