摘要：

A dual-port antenna with shared radiator and self-decoupling characteristics is proposed. The feed position of the two ports is asymmetrically arranged for the radiator. The working principle of the proposed dual-port antenna is analyzed by using the equivalent transmission line theory model. The analysis results show that the high isolation characteristic is realized when the two ports of the antenna satisfy a certain layout. The isolation between the two ports of the proposed dual-port antenna is better than 16 dB across the 3.4 similar to 3.6GHz. The envelope correlation coefficient is less than 0.042. Based on the dual-port antenna, a set of 8 x 8 MIMO antenna array was designed and measured. The isolation of the proposed 8 x 8 MIMO antenna array is better than 15 dB between all ports, the total efficiency is 38.75% similar to 87.5% with an average efficiency 64.58%.
