An important challenge in wireless communication is the reduction in size of devices. Also array size reduction has attracted increasing interest in recent years. Placing elements of an antenna close to each other is one way to reduce the total size of an antenna. However, one of the factor called mutual coupling depends on inter element separation and relative orientation. Mutual coupling is the major limiting factor of MIMO systems which arises mainly due to the smaller spacing between multiple antennas. Thus, within a compact structure of an antenna, reduction in mutual coupling in microstrip antennas is a major challenge. This paper presents simulation and design of a compact tapered triangular 2x2 multi input multi output patch antenna for reducing mutual coupling. This proposed system is applicable in the area of WLAN (2.4 GHz–2.5 GHz/5.2 GHz–5.8 GHz) and WiMAX (2.3 GHz–2.6 GHz/3.3GHz–3.8 GHz/5.7 GHz–5.85 GHz). Good agreement has been achieved between measured and simulated results.
