| Abstract | ||
| This study introduces a detailed design architecture and analysis of a modified half disc monopole Ultra-Wideband (UWB) (3.110.6- GHz) antenna elementused to build a multiple-input multiple-output MIMO with extra hybrid polarization and radiation pattern diversity. Three MIMO configurations demonstrated with full measurements for the scattering parameters and far-field antenna pattern are studied. A detailed comparative study was introduced between three different MIMO configurations to illustrate the effect of hybrid diversity techniques on MIMO performance. Analytical calculations performed to estimate various parameters such as Envelope Correlation Coefficient (ECC), Diversity Gain (DG), Total Active Reflection Coefficient (TARC), and channel gain matrix is deduced to fully describe the antenna system channel capacity performance in a full duplex telecommunication system. The MIMO parameters were obtained using both the scattering parameters and the farfield results. The enhancement in the MIMO performance comes along with the appropriate size of the antenna and improves the mutual coupling between MIMO elements. | ||
