An ultrawideband (UWB) multiple input and multiple output (MIMO) antenna having shared radiator with dual band rejection characteristics is presented in this article. The proposed antenna is based on the concept of dual polarization. The antenna consists of two tapered CPW feeds printed on one side of the substrate and a circular shared radiator on the other side. The radiator is shared between two antenna elements. High isolation between the antenna elements is achieved by introducing a rectangular slot in the circular radiator and an inverted Y ‐ shaped stub on the ground plane at an angle of 45°. The proposed antenna rejects the WiMAX and wireless LAN band of frequencies using elliptical split ring slots in the shared radiator. The diversity performance of UWB MIMO antenna is also studied. The antenna is fabricated on FR4 substrate and has a small size of 41 mm × 41 mm. The simulated and measured results are in good agreement which demonstrate its potential use in UWB portable devices. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:2886–2891, 2015
