Title:
ANTENNA DEVICE, AND ELECTRONIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/227814
Kind Code:
A1
Abstract:
The present application provides an antenna device and an electronic apparatus. The antenna device comprises: a first antenna unit and a second antenna unit disposed adjacently; a first decoupling network having an input port, an output port, a first connection port, and a second connection port, wherein the output port is connected to the first antenna unit, and the input port is used to connect a first feed source; a second decoupling network having an input port, an output port, a first connection port, and a second connection port, wherein the output port of the second decoupling network is connected to the second antenna unit, and the input port of the second decoupling network is used to connect a second feed source; a first decoupling transmission line connecting the first connection port of the first decoupling network and the first connection port of the second decoupling network; and a second decoupling transmission line connecting the second connection port of the first decoupling network and the second connection port of the second decoupling network. The present application improves isolation between the antenna device and an electronic apparatus.
