摘要：

In this study, a compact ultrawideband (UWB) multiple-input-multiple-output (MIMO) antenna with reconfigurable band notch characteristics is presented. The key feature of the antenna is its novel dual-band notch technique which blocks worldwide interoperability for microwave access or wireless local area network band interference. The UWB-MIMO property is achieved by two square monopoles separated by grounded multi-branch T-shaped stub. The reconfigurable dual-band notch operation is performed by PIN diodes integrated in a parasitic resonant structure in the ground plane. The antenna has a compact size of 40 x 20 mm(2), with the operating frequency band of 3-11 GHz, where port isolation is better than 15 dB. The MIMO performance is ensured by calculating envelope correlation coefficient for the isotropic, indoor and outdoor environment.
