摘要

A novel structure combined of an I-shaped microstrip line and eight slots etched fromrnthe ground plane is proposed to decouple both E-plane and H-plane antenna arrays.rnFive types of antenna arrays at 5.25 GHz with different linear placements are discussedrnfor the first time and the decoupling structure is valid to them all. The edgeto-rnedge distances of the H-plane arrays and the E-plane arrays are 0.09λ0 and 0.17λ0,rnrespectively. Simulated and measured results indicate that the combined structure canrneffectively reduce the mutual coupling, with the maximum values reaching to 22.62,rn28.41, 21.04, 22.33, and 26.04 dB for five types, respectively. The proposed structurernis potential in the application of multielement arrays and communication MIMOrnsystem.
