Abstract:An ultra-wideband (UWB) multiple-input multiple-output (MIMO) antenna that is programmable is shown in this work. The frequency range covered by the described antenna is 11:1 from 440 MHz to 5 GHz. while maintaining a small footprint for MIMO applications. By combining a UWB monopole antenna with a tunable matching network via two distinct signal routes from a singl e feed point, the ultrawideband functionality is achieved. The UWB antenna functions across the remaining frequency range, whereas the adjustable part spans the 440 MHz to 700 MHz range. Orthogonally positioning two identical UWB antennas on the same substrate allows for the construction of a MIMO configuration and polarization diversity. The presentation of MIMO diversity parameters and the reflection coefficient for the complete operation region is made.
