Abstract
In this paper, MIMO antenna is designed, which consists of two planar symmetrical monopole antennas and T-slot adjoining to the common ground plane. The return loss is below −15 dB for a wider bandwidth. The overall antenna size is low as 35 mm × 22 mm but the effect of the mutual coupling among the antenna elements is reduced and is below −10 dB in lower range and below −20 dB at higher frequency range within wider frequency range of 4–10.5 GHz. The resonant frequency is taken as 4.4 GHz. The designed MIMO antenna has two ports whose reflection coefficient behaves as shadow of one another which is considered to be better in terms of efficiency. In this process, the maximum gain achieved is approximately 2 dB. The design has been verified and is ready for fabrication so that the MIMO antenna can be practically used. The design has been simulated using Ansoft HFSS software 15.0. The various parameters like S-parameters, VSWR, gain and radiation pattern are shown.
