摘要

This paper presents a novel technique to change the impedance characteristics of patch antenna to achieve multi-band. The proposed structure is based on the metamaterial concept. By replacing the conventional substrate of patch antenna with metamaterial, the impedance characteristics can be effectively changed to produce multi-band property. The design is based on the dispersive characteristic of the substrate by using metarnaterial structure. To validate the proposed approach, numerical and experimental results are presented; the results show the validity of our approach.
