Title:
MULTI-INPUT MULTI-OUTPUT ANTENNA SYSTEM AND MOBILE TERMINAL
Document Type and Number:
WIPO Patent Application WO/2018/119944
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 MIMO antenna system comprises a substrate and two or more antenna structures. The substrate comprises a feed source and a grounding point. Each of the antenna structures comprises: a first layer structure; and a second layer structure arranged between the first layer structure and the substrate. The first layer structure comprises a first metal attachment plate and a first short-circuited component. The first metal attachment plate comprises a feed point connected to the feed source and a first grounding feed point. Two ends of the first short-circuited component are connected to the first grounding feed point and the grounding point, respectively. The second layer structure comprises a second metal attachment plate coupled to the first metal attachment plate and a second short-circuited component. The second metal attachment plate comprises a second grounding feed point. Two ends of the second short-circuited component are connected to the second grounding feed point and the grounding point, respectively. By coupling the first metal attachment plate and the second metal attachment plate, the embodiment can reduce coupling between respective antenna structures, thereby increasing isolation between the respective antenna structures.
