| Abstract | ||||
| The optimum configuration of antenna diversity can be designed by considering the characteristics of both the antenna effective gain (Ge) and the correlation coefficient (ρe). Therefore, this paper introduces a procedure to evaluate and optimize antenna diversity parameters. The proposed procedure is based on numerical calculations of relevant derived formulas for Ge, ρe, and the normalized mutual resistance R12 between diversity antenna ports. Moreover, different co-polar, and cross-polar antenna pattern E-plane and H-plane cuts, are used to evaluate and analyze the correlation characteristics, and hence optimum antenna diversity configuration is obtained. The developed procedures are then used to analyze parallel-dipoles space diversity antenna system. | ||||
