    Compact UWB Patch Antenna with Open-Loop Resonator for Dual-Band Rejection
    (Horizon House, 2025) Fortas, Ibrahim; Ayad, Mouloud; Zoubiri, Bachir
    A novel approach to the design of a compact UWB patch antenna with improved rejection capabilities integrates a dual-ellipse structure in the patch geometry fed by CPW. It also employs four open-loop resonators to selectively target undesirable frequency bands, specifically WLAN (5.2 to 5.8 GHz) and the satellite downlink band (7 to 8 GHz). Experimental results closely align with the simulation, verifying the effectiveness of the open-loop resonators in enhancing rejection.

    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
