A UWB MIMO spatial design effect on radiation pattern

Attractive features of emerging Ultra-wideband (UWB) and Multi-Input Multi- Output (MIMO) technique are outlined and special design effects are described. The proposed antenna is basically comprised of two patch elements integrated on the same substrate. In the sense of optimum inter-element spacing, initial analysis on antenna configuration has been made towards the reflection coefficient, mutual coupling and correlation coefficient. Furthermore, a proposed spatial design antenna on radiation pattern effect also has been presented. The proposed antenna design achieved the required impedance bandwidth over the entire frequency range of 3.1 GHz to 10.6 GHz under the acceptable S11 of less than 10 dB.
