Abstract

This paper presents the design of a 2.65 GHz MIMO antenna with three equilateral triangular microstrip patches as the antenna elements. The wide-beam characteristics of a triangular-patch antenna, combined with the high gain of each antenna element, improve the SNR and interference rejection of the MIMO system. Through the analysis of mutual coupling and correlation between each pair of antenna ports, it is shown that the antenna achieves good polarization and directivity diversity. A high diversity gain can therefore be achieved.
