A multiple‐input‐multiple‐output (MIMO) antenna with dual polarization, operating in the UWB frequency range is proposed. The radiator is shared by the two antenna elements, which greatly reduces the overall size of the MIMO antenna system. Slots are etched in the radiator to achieve the desired isolation among the elements. Dual polarization characteristics of the radiator are attained in the far‐field due to orthogonal currents. The comparison of simulated and measured results show that the proposed MIMO antenna operates on a wide range from 3 to 11 GHz with a low mutual coupling (<−15 dB) and also a low envelope correlation coefficient. A prototype was fabricated on low loss Rogers TMM4 laminate measuring only 25 × 27 mm 2 , which is a very compact design. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:163–166, 2016
