A novel four-element MIMO antenna operating at millimeter wave band is proposed. The half-mode substrate integrated waveguide (HMSIW) cavity backed slot antenna is used as the element to realize a compact structure, high radiation efficiency and interelement isolation. The simulated relative impedance bandwidth is 29.6% from 23.5–31.0GHz for S11<−10dB. And the isolation is lower than −22dB across the operating band without any additional coupling reduction structure.
