    A compact coplanar waveguide fed UWB antenna for energy harvesting applications
    (IEEE, 2021) Jameel, Maryam S.; Mezaal, Yaqeen Sabah; Atilla, Doğu Çağdaş; Hussein, Ehab
    A new monopole antenna design fed by the Coplanar Wave Guide (CPW) is proposed for energy harvesting applications using FR4 substrate. The antenna presented here functions with an impedance bandwidth of 10 GHz from 3.27 to 13.27 GHz. Dimensions in total are 27*25 mm2 . The antenna was designed with the help of the CST Microwave Studio 3D EM software simulation and analysis. It may be used for ultrawideband (UWB) and other radio systems.

    Compact microstrip antenna for ultra-wideband applications using SIR feeder
    (IEEE, 2021) Hussein, Ehab; Mezaal, Yaqeen Sabah; Bayat, Oğuz
    A compact ultra-wideband patch antenna is presented in this paper. In this article, we will discuss the antenna design and performance. FR-4 substrate with dimensions of 10x20x1.5 mm3 and permittivity of 4.3 is used to mount the antenna. We have designed a new antenna that utilizes a slotted patch resonator, a tri-sectional SIR feeder, and a ground plane that is reduced on an FR4 substrate. It turns out the antenna's frequency range of 3.96 – 9.2 GHz, according to the S11 results. CST Microwave Studio 3D EM simulation and analysis software was used to design the antenna. It can be used for UWB and other radio communication systems. Simulated S11 consequences are fairly agreed with the measured ones.

    New printed slot antennas with etched SIR components in the ground plane
    (Taylor & Francis Ltd, 2022) Mezaal, Yaqeen Sabah
    In this study, two new printed slot antennas have been simulated and fabricated using a single layer of FR4 substrate for modern wireless applications. The first printed slot antenna with etched stair-step topology in the ground plane is proposed to achieve the single-band operation. This topology is based on two components of asymmetrical step-impedance resonator (SIR) and one component of symmetrical SIR. The first designed printed slot antenna satis?es the requirements of WLAN applications at 5.75 GHz. The second printed slot antenna is a developed version of the first one with one inserted component of symmetrical SIR and one asymmetrical SIR component to be operated as a multiband antenna applicable for WiMAX, WLAN, and X-band downlink satellite systems at 3.5, 5.75, and 7.75 GHz, respectively. The proposed antennas have small sizes, and competitive electrical specifications than many reported SIR and non-SIR antennas in the literature.
