Abstract

In this paper, a four-port multiple input multiple output (MIMO) antenna with half ground for multiband application has been presented. The four antennas are planned to be assembled on a single FR4 substrate of thickness 1.57mm with adequate isolation between them to produce a four-port MIMO antenna that can operate for multiband applications. The proposed MIMO antenna is simulated in ANSYS HFSS software. In the proposed antenna, the ground has been modified to improve the antenna parameters. For the proposed four-port MIMO antenna with half ground for multiple band applications, the achieved return loss is -33.88dB, -28.31dB, -30.56 dB, -29.45dB and -26.05dB; Insertion loss are -26.12dB, -19.67 dB, -27.29dB, -23.53dB and -24.62 dB; VSWR are 1.05 mag, 1.08 mag, 1.06mag, 1.07mag and 1.10mag for corresponding frequencies of 1.50GHz, 3.62GHz, 5.59GHz, 6.75GHz and 7.47GHz and gain of the proposed antenna is 4.3dB.
