A Compact Planar Monopole UWB MIMO Antenna Design with Increased Isolation for Diversity Applications

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