Abstract: The present disclosure provides a multi-antenna system comprising at least two antenna units and a neutralization line for connecting two adjacent antenna units, and the neutralization line is provided with an inductor element. The invention also provides a mobile terminal. The multi-antenna system and the mobile terminal provided by the present disclosure could significantly increase the isolation degree between the antenna units by providing a neutralization line between the two adjacent antenna units for connecting the same and providing an inductor element on the neutralization line, thereby reducing the mutual coupling interference between antenna units and improving the antenna performance.

Abstract: The present disclosure provides an antenna system applied to a mobile terminal. The mobile terminal includes: a housing; a main board received in the housing and including a power amplifier; a plurality of antenna units; and a transmission circuit board received in the housing and configured to electrically connect the power amplifier with the plurality of antenna units. The transmission circuit board includes a plurality of transmission lines configured to feed the plurality of antenna units with power. Compared with the related art, the antenna system provided by the present disclosure, by additionally providing a transmission circuit board dedicated to connecting a power amplifier with an antenna unit, eliminates the necessity of routing on a main board to connect the power amplifier with the antenna unit, so as to facilitate wire arrangement and avoid signal interference between the respective traces.
