ABSTRACT

A compact multiband four port multiple-input multiple-output (MIMO) antenna is presented using rectangular microstrip patch antenna. This work uses octagon complementary split-ring resonator (OCSRR) loaded on its ground plane. The designed MIMO antenna resonates at multiband frequency 2.36 Hz, 4.52 GHz, and 5.9 GHz, respectively, and for its isolation −22.09 dB, −24.22 dB, and −17.23 dB with overall bandwidth 344.5 MHz. The results of this designed MIMO antenna system shows a good isolation, bandwidth, peak gain, voltage standing wave ratio, and low envelop correlation coefficient which is promising for next generation wireless application systems.
