Title:
MULTI-INPUT MULTI-OUTPUT ANTENNA SYSTEM AND MOBILE TERMINAL
Document Type and Number:
WIPO Patent Application WO/2018/119946
Kind Code:
A1
Abstract:
The application relates to the field of antennas, and specifically, to a multi-input multi-output (MIMO) antenna system and a mobile terminal. The antenna system comprises: a substrate having a length direction and a width direction; and a first metal piece and a second metal piece arranged opposite to each other and along the width direction of the substrate. The first metal piece, the second metal piece, and the substrate are radiators in the MIMO antenna systems. Gaps are provided between the substrate and the first metal piece and the second metal piece, respectively. The first metal piece comprises thereon a first feed point. A first matching circuit is configured between the first feed point and the substrate. The first feed point and the substrate are electrically connected to two sides of the first matching circuit. The second metal piece comprises thereon a second feed point. A second matching circuit is configured between the second feed point and a second substrate. The second feed point and the substrate are electrically connected to two sides of the second matching circuit. The MIMO system in the embodiment has favorable orthogonality, a low correlation coefficient, and high a communication rate of a communication system.
