A two‐element diversity planar antenna for a multiple‐input multiple‐output application is proposed. By adopting two Y‐shaped radiators, the antenna provides wideband impedance matching characteristics over the desired frequency band. To reduce the mutual coupling between two radiating elements, three stubs are inserted in the ground plane. Good impedance matching and improved isolation characteristics are observed. The measured impedance bandwidth of the proposed antenna ranges from 2.27 GHz to 10.2 GHz for a return loss of less than 10 dB. Parametric analysis has been conducted to investigate the effect of radiator length and the insertion of stubs on the impedance bandwidth and isolation characteristics. © 2008 Wiley Periodicals, Inc.
