Abstract
This letter presents a two-port dual-band multiple-input-multiple-output (MIMO) antenna, which is achieved based on a non-radiation passive circuit. The circuit is composed of two pairs of open-ended stubs and a transmission line connecting them. The decoupling condition of S21 = 0 is deduced, thus a good isolation is achieved. Then this non-radiation circuit is further designed to be a structure with enough radiation without affecting the character of port isolation. Since the implementation of port isolation does not adopt complex decoupling network or decoupling structure, the process of design is simple and effective. The simulation and physical demonstration obtain good agreements for the proposed dual-band MIMO antenna.
