摘要：

A multiband dual-antenna design for multiinput-multi-output (MIMO) operation in mobile terminals is presented. The proposed dual-antenna system is composed of two symmetric antenna elements, and each of them consists of one driven branch and one parasitic branch. The dual-antenna system uses a simple decoupling structure to reduce the mutual coupling between two antenna elements. The impedance bandwidth with active vertical bar S-11 vertical bar <=-6dB covers two frequency bands of 700-960 and 1710-2690 MHz, and the isolation between the two antenna elements is better than 10dB within most of the operating bands. The envelop correlation coefficient, mean effective gain, diversity gain, and channel capacity are calculated exhaustively based on the three-dimensional radiation patterns. The results show that the antenna system has good diversity performance, which makes it suitable for MIMO operation in mobile terminals.
