The antenna is designed on FR4 material and simulated results by HFSS software are provided. The simulated results show that the proposed MIMO antenna achieves the return loss of less than -10 dB and the mutual coupling of less than dB between elements in a bandwidth ranging from 2329 to 2495 MHz, which entirely covers WLAN frequency band allocated from 2400 MHz to 2480 MHz. The obtained results indicate that the proposed antenna is a good candidate for MIMO applications. 1. Introduction Multiple-Input-Multiple-Output (MIMO) technology has been widely applied for wireless communication because it can offer significant increases in data throughput and link range without using additional bandwidth or transmit power [1-9]. By using multiple antennas in both the transmitter and receiver, the MIMO technique can detect multiple independent channels in free space, which can achieve a higher capacity of a link compared to the classic single-antenna design. Due to this unique feature, MIMO has been adopted in all major wireless standards such as IEEE (Wi-Fi), 4G, 3GPP Long Term Evolution, WiMAX and HSPA+ [2]. However, a multi-antenna system has just the best performance when the mutual coupling among the antenna elements is low because a .
