    Design and Simulation for Triple-Band Metasurface Slot Antenna
    (American Institute of Physics Inc., 2023) Gatea, Q.M.; Alkhafaji, M.A.; Güneser, M.T.
    The proposed antenna works well in three resonant frequencies for various applications such as Wi-Fi and WiMAX, with good rejection of other frequencies to prevent interference between these applications' work and other applications operating in the same bandwidth. There are three bands: 2.7 GHz, 7.27 GHz, and 8.67 GHz, with respective gain values of 7.19 dBi, 8.96 dBi, and 1.97 dBi. The cells are created by connecting two opposed letters C of varied sizes so that the smallest gets contained within the biggest. The standard antenna was integrated with the metasurface layer using Fabry-Pérot resonating cavity theory, and there is an air gap between them. The simulation was carried out using the CST program. © 2023 American Institute of Physics Inc.. All rights reserved.

    Wideband and High Gain Antenna of Flowers Patches for Wireless Application
    (Springer Science and Business Media Deutschland GmbH, 2023) Gatea, Q.M.; Alkhafaji, M.A.; Guneser, M.T.; Obaid, A.J.
    Because of its modest properties, the slot antenna has become an unsuitable contender in many applications. To achieve high gain, small size, and a wide frequency range in the proposed antenna, two layers of flower-shaped cells are positioned at various heights according to Al-Fabry–Perot theory. The improvements in antenna performance extended to the feed line and the slot drilled by the ground plate, allowing the amount of current flowing to be controlled. The number of cells in each of the metasurface layers above the typical antenna is 4 × 4. The antenna has a peak gain of 9.8 dB and a bandwidth of 2.6 GHz between 4.33 and 6.93 GHz. The CST software was used to carry out the simulation procedure. The antenna’s characteristics have made it an excellent contender for wireless applications. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
