Abstract

In this paper, a compact dual-element MIMO antenna is presented for 5G mobile terminal applications. Each element has two driven monopole branches and one parasitic ground branch. All the branches operate at the \lambda/4 mode. The two elements are placed at the top and bottom corners of the board. The -10 dB bandwidth is sufficient to cover the 1710-2690 MHz and 3400-3600 MHz bands, also with port isolation higher than 16 dB. In addition, the theory of characteristic modes is used to analyze the internal mechanism of port isolation.
