A novel dual-band MIMO antenna with two rings for WIMAX applications

Abstract

A new equivalent-circuit model consisted of three transmission lines is proposed and a decoupling equation is derived for determining the electric parameters of required the three transmission lines. In order to further verify the feasibility of the equivalent circuit, a novel dual-band two-port multiple-input-multiple-output antenna with two rings working in the 2.35- and 3.5-GHz bands of the WIMAX is presented. The details of the building circuit model and the experimental results and discussion are given.
