Abstract

This paper presents one miniaturized circular patch antenna (1-CPA) instead of two CPAs to generate multimode patterns for multiple-input multiple-output (MIMO) communication systems. A suitable material composition using ferrite substrate materials is proposed. The proposed ferrite 1-CPA is tested using the FEKO simulator, and it is found that the size of the proposed ferrite 1-CPA can be significantly smaller, e.g., 25.7 times, than that of the recently developed dielectric two-CPAs stacked. However, the bandwidth of the proposed ferrite 1-CPA should be sacrificed by one quarter.
