    Metamaterial-Based Mm-Wave Phased Array for Broadband Cellular Networks
    (Institute of Electrical and Electronics Engineers Inc., 2023) Amar, A.S.I.; Parchin, N.O.; Fawzy, Diaa E.; Allam, A.M.M.A.; Eid, A.M.; Soliman, M.A.
    A new broadband phased array antenna with wide-scan and high-gain beam-scanning are desirable to meet the requirements of future cellular networks. This paper discusses the characteristics of a new beam-steerable array design having broad bandwidth for 5G communications. The discussion is focused on smartphones, due to their small size and complexity. The design procedure is straightforward and accomplished on a mainboard of future smart handheld devices. The introduced phased array design involves eight metamaterial-based dipole resonators with a 1×8 linear form. The resonators have small sizes with microstripline feedings. For -10 dB, the design represents 28-38 GHz covering several bands in the 5G spectra. © 2023 IEEE.

    Mimo Slot Antenna With Polarization Diversity and Dual Notched Bands for Uwb Applications
    (Institute of Electrical and Electronics Engineers Inc., 2023) Parchin, N.O.; Amar, A.S.I.; Fawzy, D.E.; Allam, A.M.M.A.; Eid, A.M.; Ibrahim, A.G.A.
    This paper introduces a 4-port MIMO slot antenna system with dual notched bands, which is designed for future wireless communications. The antenna structure consists of four modified U-shaped radiation stubs with a shared ground plane, arranged in a planar form. The results demonstrate that the antenna operates effectively across frequencies ranging from 2.1 to 10.7 GHz, covering the entire ultra-wideband (UWB) spectrum. Moreover, two notched filtering characteristics have been incorporated at 3.3 to 4.2 GHz and 5 to 6 GHz, utilizing modified radiation stub resonators. These notches effectively suppress interference from C-band, WLAN, and WiMAX interfaces. The performance of the proposed antenna design has been thoroughly evaluated in terms of its fundamental characteristics. The results show that the antenna achieves satisfactory scattering parameters, 3D radiation patterns, efficiency, and gain levels. The designed UWB antenna system fulfills the requirements for MIMO and diversity applications. © 2023 IEEE.
