Abstract
A compact 6-port MIMO antenna consisting of equilateral triangle elements have demonstrated in order to miniaturize the size and reduce the mutual coupling of antenna elements due to its geometrical shape. 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 -12.5 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.
