Benchmark Diversity Results for Generic Spaced Patch Antennas

MIMO communication has become a standardized technique but the methodology for designing the required diversity antennas is not yet widely understood. Parameters from models of diversity action are often used by designers without full regard to the inherent assumptions of the models behind the parameters. This paper presents diversity evaluation of a generic dual patch diversity antenna in terms of one widely used parameter, the envelope correlation coefficient (ECC). The calculation of the ECC is undertaken via the inner product of the antenna embedded far-field radiation patterns and circuit coupling parameters (s-parameters). These results can be used to benchmark simulations used in diversity antenna design.
