Abstract

This paper presents an approach to reduce the mutual coupling (MC) between two H-shaped patches in a probe fed multi-input multi-output (MIMO) antenna. The antenna covers the frequency spectrum from 3.46 to 3.69 GHz with an impedance bandwidth of 6.5%. The proposed antenna is incorporated with a modified EBG structure as an isolator to increase the port isolation. The isolator reduces mutual coupling of about 30.5 dB between the two ports. The antenna offers very low envelope correlation coefficient (ECC < 0.0023) and provides a good radiation pattern in E- and H-plane.
