Abstract

In this paper, a two port “club” shaped MIMO antenna is proposed for next generation wireless systems. In the proposed antenna design, slots were introduced in the ground plane and minimal spacing was maintained, which collectively contributed to enhanced overall performance. Furthermore, the proposed MIMO antenna is designed on Rogers RT/duroid 5870(tm) substrate with an overall dimension of 24mm × 12mm × 0.5mm (2.93?_0 × 1.46?_0 × 0.06?_0, where ?_0 is the free space wavelength at the resonating frequency). The proposed antenna resonates at 36.63 GHz and achieves a wide bandwidth of 5.46 GHz (33.57 - 39.03 GHz). In addition to it, the proposed antenna achieves an isolation of < -27.27 dB, peak gain of > 5 dB and a high radiation efficiency of > 98%. Moreover, in terms of diversity parameters, the proposed MIMO antenna achieves acceptable results with envelope correlation coefficient < 0.0005 and diversity gain < 10dB. Thus, it can be concluded that our proposed antenna may be a suitable candidate for Ka band, 5G mm-wave and next generation wireless systems.
