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.
