A Compact 2-Element Side-Edge MIMO Antenna For 5G Applications

A novel miniaturized printed antenna placed on the side edge is investigated for fifth-generation wireless applications. The proposed two-element antenna is configured for multiple-input – multiple-output (MIMO) to cover the frequency band (3.625 – 3.77) GHz, with a resonant frequency at 3.7 GHz. Various locations for the indicated two-element antennas are examined in terms of scattering parameter S11, mutual coupling |S21|, radiation pattern, and gain. The MIMO antenna achieves a very low envelope correlation coefficient (ECC). The proposed antenna achieves a maximum gain of 3.38 dB with isolation better than 25 dB in the operating frequency range.
