5G dual-band slotted SIW array antenna

A dual-band slotted substrate-integrated waveguide four-element array antenna for the 5G communication system is presented in this manuscript. Two longitudinal slots are responsible generating frequency bands of 28 and 38 GHz. The proposed designed on substrate duroid 5880/Rogers having a loss tangent dielectric constant 0.003 2.2, respectively. developed single-element design at GHz provides 6.35 dBi gain, while it 7.3 gain simulation carried out with CST Microwave Studio, 2018. To accomplish high an optimized parallel feeding network same that covers (27.6–28.1 GHz) band (37.9–38.69 GHz). attains radiation efficiency 88.08% 12.7 84.44% 15.5 band.
