A dual-polarized wideband aperture antenna operating in millimeter wave band for MIMO applications in 5G mobile communication systems is presented. Using the tapered aperture hybrid structure and the backed-cavity design on PCB technology, the antenna achieves dual-polarized and unidirectional broadside radiation. The proposed antenna also possesses a high port-to-port isolation of better than 26dB and a broad impedance bandwidth of 25%. This work further extends to a 4-element array.
