Two-Element Pharaonic Ankh-Key Array Antenna Design, Simulation, and Fabrication for 5G and Millimeter-Wave Broadband Applications

In this paper, a two-element Pharaonic Ankh-Key array antenna is proposed. The array antenna is designed, simulated and fabricated to enhance the new technologies upcoming in the market. The multiband array antenna can operate in 24 GHz band, 28 GHz band, 37 GHz band, 39 GHz band, 47 GHz band, E-band, W-band, and D-band with peak gain between 7.8 dBi to 12.3 dBi along the resonating spectrum. The array antenna is a single layer of two-element antenna separately fed by
$50\Omega $
microstrip line with dimensions 18.7 mm
$\times18.5$
mm and a height of 0.787mm Rogers/Duroid RT 5880 of
$\varepsilon _{r} =2.2$
and
tan

$\delta =0.0009$
which was easily fabricated with a very low cost compared to the existing antennas in the market making it a very promising candidate for 5G and beyond technologies MIMO applications as it operates in almost all band between 23 GHz and 140 GHz. The antenna is designed and simulated using CST Suite, Ansys HFSS, and IE3D Mentor Graphics simulators then the simulated results where compared to the measured results achieving a very good agreement.
