Abstract
This article proposes a multiple input multiple output (MIMO) antenna for 5G-based vehicular communication applications. The designed MIMO antenna consist of two element iterated T-shape antenna with defected ground structure (DGS) and split ring resonator. The antenna providing reflection coefficient S11 s11 ≤10 dB and bandwidth of 6.3 and 3.96 GHz over the frequency range of 26.83 to 33.13 GHz and 34.17 to 38.13 GHz, respectively. For the suitable future vehicular millimetric wave communications, this antenna achieved resonant frequencies at 28, 33, and 37 GHz. The designed antenna has achieved peak gain of 7.11 dB in operating band. It is fabricated on 12 x 25.4 x 0.8 mm3 Rogers RT duroid 5880 substrate with dielectric constant (εr) of 2.2. The antenna is placed on vehicle in virtual environmental using ANSYS SAVANT tool and the simulated results are showing good matching with the measured results of proposed MIMO antenna.
