This letter presents a compact multiple‐input multiple‐output (MIMO) ultrawideband (UWB) antenna, and this MIMO antenna consists of two coplanar waveguide ‐fed monopole antenna elements and an improved ground‐plane. These two antenna elements are symmetrically arranged on a FR4 substrate with dimensions 33.8 × 29 × 0.8 mm 3 . The improved ground‐plane has several ground stubs and windows, and they are applied as decoupling structure to improve the isolation as well as impedance matching. Simulation and measurement are used to study the antenna performance, results show that the antenna has a wide impedance bandwidth of 2.2–10.6 GHz with |S 11 | ≤ −9 dB, low mutual coupling of less than −12 dB and −17 dB over the range of 2.5–4.2 GHz and 5.6–10 GHz, respectively, and LTE 2500 and UWB operation bands can be covered successfully. © 2015 Wiley Periodicals, Inc.
