    Design and simulation of millimeter-wave broadband modified ankh-key antenna for 5G and beyond technologies applications
    (Elsevier B.V., 4/22/2021) Rashad, N.M; Klialaf, A.A.M
    In this paper, a modified Pharaonic Ankh-Key antenna is proposed to support modem technologies and enhance the usage of 5G and next generations applications providing better performance compared to the previously designed Ankh-Key antenna [3]. The multiband antenna can operate in 28GHz band, 37 GHz band, and all bands from 49 GHz to beyond 140 GHz with peak gain between 6.9 dBi to 10.2 dBi along the operating spectrum. The single layer antenna is simply designed with dimensions 12.75 mm x 18.7 111111 x 0.787 111111 using Rogers/Duroid RT 5880 of er = 2.2 and tanS = 0.0009 promising a lower cost and easy-to-fabricate antenna compared to the existing commercial antennas. The antenna is simulated using Ansys HFSS and CST suite simulators and the results where compared to the previously designed Ankh-Key antenna achieving much better performance and wider band widths.
