Summary:A modern mm-wave antenna structure was introduced and simulated using features of CST microwave studio to serve the applications of 5G mobile communications. This antenna is known as compact of Quasi-Yagi with well-matched impedance bandwidth laying between 29.58 GHz and 33.63 GHz supporting 4 GHz of operating bandwidth with S11 parameter of -41 dB at 31.5 GHz and less than -30dB of mutual coupling for array structure. The antenna is printed on a substrate made of Arlon Ad 350 with thickness of 0.8 mm, dielectric constant ε r = 3.5 and δ = 0.003. The antenna is powered using coaxial cable with vias crown surrounding the feeding area. Moreover, phased linear and planner array configurations are used with order of 2x1, 8x1 and 2x2 to improve the realized gain providing more than 9.02 dBi and 15 dBi of directivities with wide range of pattern scanning. The results are simulated using CST software.
