A compact UWB–MIMO antenna with WLAN band notched characteristic is presented. UWB coverage is achieved with two closely spaced planar–monopole elements on the top side of the dielectric substrate with a truncated ground‐plane etched on the bottom side. Isolation between the antennas is achieved by creating a current path to decouple energy between the radiation elements using a T ‐shaped ground stub. Notched frequency band between 5.15 and 5.85 GHz is achieved with a parasitic rectangular strip on the bottom side, which is connected to the radiating patch through a via hole. This approach yields a highly compact antenna design having dimensions of 22 × 29 × 0.8 mm 3 . Simulated and measured results confirm the antenna has an impedance bandwidth of 7.6 GHz from 3.0 to 10.6 GHz making it suitable for UWB MIMO systems. © 2017 Wiley Periodicals, Inc.
