Abstract

In this paper, multiple-input multiple-output (MIMO) millimeter-wave wide scan beam 5G antenna array for 28 GHz application in the mobile terminals is presented. The MIMO antennas operate in 25-30 GHz in the end-fire direction. The antenna array composed of eight-element tapered tilted dipole antennas. The proposed antenna array can scan the beam in a wide coverage region from ± 80 degrees in wide operating bandwidth with scan loss better than 3 dB. The antenna coverage efficiency is better than 94 %, 78%, and 52 % for minimum realized gain of 0, 5, and 8 dBi respectively. The antenna has a good impedance matching (S11< -10 dB) and mutual coupling better than -28 dB in whole operating frequency bands from 25-30 GHz.
