High Gain 16 Ports MIMO Antenna at 60 GHz for Millimeter Wave Applications

In this paper, a high gain 16 ports MIMO antenna is designed at 60-GHz for millimeter wave applications. The proposed antenna consists of 16 ports, each port consisting of 1 x 2 antenna array. The designed MIMO antenna achieves a bandwidth (|S11| <; -10 dB) of 1.5 GHz, covering a band from 59.15-60.65 GHz, with gain of 19.86 dBi and directivity of 21.59 dBi . It gives the best results compatible with IEEE 802.11ad standard for 60GHz wireless communication. Comparative analysis is carried out by adding number of ports to the antenna. The high gain antenna system is designed on 0.2 mm FR4 substrate with dielectric constant of 4.4 and loss tangent of 0.0004. The size of the proposed antenna is 48.56 mm × 21.82 mm.
