A Planar MM-Wave Beam-Steerable Array Antenna for 5G Mobile Terminal Applications

In this paper, a 5th-Generation (5G) wireless communication applicable beam-steerable slot antenna array is proposed. Fabricated on the Rogers RT5880 substrate, the antenna array has eight slot antenna units that are suitable for the bottom of the handheld device. The simulation results obtained by Ansys HFSS show that it can work well in the frequency range of 24.2-32 GHz and 37-42.2 GHz. In the above frequency ranges, the S11 parameter of the antenna is less than -10 dB. Also, the antenna array can achieve good gain at different scanning angles in its -10dB impedance bandwidth.
