摘要：

??? A compact planar multiple input multiple out-put (MIMO) antenna with four elements spanning the ultra-wideband (UWB) is proposed for diversity applica-tions. The unit cells are positioned orthogonally to lower the mutual coupling by replicating the single antenna three times. A 35 ?? 35 ?? 1.6 mm3 UWB MIMO antenna is provided with a 50-?? impedance microstrip line on a 1.6-mm thick FR4 substrate. In the radiator and ground plane, some modifications are made to achieve the operating limits of this antenna between the frequen-cies of 3.1-10.6 GHz, thereby covering the entire fre-quency spectrum of the UWB with compact size. We conclude from the calculated results that the proposed antenna has high performance characteristics appropri-ate for UWB wireless indoor communication and diver-sity applications with compact size.
