| Abstract: | Compact UWB-MIMO antenna with mutually perpendicular decoupling structure was proposed.The antenna consisted of four ear-like planar monopole antenna elements.By adding the inverted L-shaped structure with the parallel strips in the ground,its bandwidth was greatly widened.At the same time,the isolation between the antenna ports was increased,too.The simulation and measurement results showed that the return losses and the isolations of the designed antenna all were below-10 dB and-20 dB across the UWB of 3.1-10.6 GHz,respectively.Furthermore,gains,radiation efficiencies,the radiation patterns and the correlation coefficients were presented. |
