Abstract
This paper presents a design methodology of newly developed dielectric embedded uniform circular array (DEUCA) for multiple-input and multiple-output (MIMO) communication systems. Compared with conventional uniform linear array (ULA), the DEUCA has improved communication performance in MIMO communication systems with its small and compact physical size and built-in orientation for wireless routers. A multi-objective evolutionary algorithm, combined with a full wave frequency domain finite element method (FEM) approach, is employed to design the DEUCA, due to the complexity of the physical structure and various conflicting performance specifications of this DEUCA. A comparison of antenna performance between the conventional ULA and the proposed DEUCA is also made.
