Abstract: in this contribution, a MIMO micro strip patch antenna with four radiating elements is designed3 at 28 GHz. The designed antenna has a very low isolation loss between radiating antenna elements. The MIMO antenna is simulated using the CST Microwave simulator. The measurement results are also shown in this paper. Both simulation and measurement results are studied to analyze the performance of the antenna. The MIMO patch antenna features such as, return loss, VSWR, gain, beam-width and radiation pattern are analyzed at a center frequency of 28 GHz. The isolation loss between the MIMO antenna elements is investigated experimentally with inter-element spacing of 3 mm. The envelope correlation coefficients among the elements, the mean effective gains, the efficiencies are also discussed. The designed antenna is planner, compact and thin so it is applicable for 5G handset.
