    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.

    Design of miniature UWB-based antenna by employing A trI-sectional sir feeder
    (Altınbaş Üniversitesi, 2021) Hussein, Ehab
    A novel ultra-wideband (UWB)-based microstrip antenna is presented in this dissertation by using a slotted patch resonator, a tri-sectional stepped impedance resonator (SIR) feeder, as well as a Reduced Ground Plane (RGP). The whole structure was realized on an FR4 substrate. The impact of incorporating several cases of ground planes on the input reflection has been thoroughly investigated under the same tri-sectional SIR feeder and by employing a slotted patch radiator. Since the complete ground plane presents an inadequate frequency response, by reducing the ground plane, the induced UWB responses are apparent while the antenna exhibits higher impedance bandwidth. The impact of both the uniform impedance resonator (UIR) as well as the SIR feeder on the input reflection has also been examined by following the same adopted reduced ground technique and using a slotted patch radiator. As a result, the UIR feeder exhibits a dualband frequency response, when a wide notched band is incorporated in the range from 4.5 – 6.5 GHz. The dual-band response of the bi-sectional SIR feeder is still apparent with a narrower notched band in the frequency range from 4 to 5 GHz. As far as the tri-sectional SIR feeder is concerned, the UWB response is discernible without recording the existence of a notched band. Additionally, the antenna displays a higher impedance bandwidth compared with the previously reported steps. Our proposed antenna configuration is designed with highly compact dimensions and an overall size of 14 × 27.2 mm2. Moreover, it operates under the impedance bandwidth of 2.86 – 10.31 GHz that can be leveraged for numerous applications where wireless systems are used. Our approach presents several advantages compared with the other reported UWB-based antennas in the literature, whereas the measured S11 pattern is in good agreement with the simulated one.
