A low-profile wideband four-corner-fed square patch antenna for fifth-generation (5G) multiple-input–multiple-output (MIMO) mobile antenna application is presented. The proposed antenna uses a single square patch to generate four uncorrelated waves over a wide band to cover 3.3–4.2 GHz (5G N77 band) with a low profile of 2.4 mm (0.03 λ at 3.75 GHz). Wideband operation is obtained by generating the half-patch TM11mode and the quarter-patch TM1/2,1/2mode for each port. The half-patch TM11mode is created by embedding two diagonal linear slots in the square patch. By further placing shorting pins along the patch's two centerlines, a square two-edge-shorted quarter-patch for each port to support the quarter-patch TM1/2,1/2mode is created, which combines with the half-patch TM11mode to form a wide operating band. Details of the proposed antenna including the experimental results are presented.
