The objective of this paper is to design a miniaturized and multiband multiple input multiple output (MIMO) antenna using slotting technique whichcan be used for many devices such as cell phones and microwave radio relay. The MIMO antenna module consists of four microstrip antennas whichare arranged in two MIMO antenna pairs. Reduction in size, multi-broadband, moderation in gain, and good efficiency are obtained. The main aimis to reduce mutual coupling while optimizing the antenna size. The present work would be aimed at designing an antenna which is used mainly forwireless applications [1].
