Title:
ANTENNA APPARATUS AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/227813
Kind Code:
A1
Abstract:
The present application provides an antenna apparatus and an electronic device. The antenna apparatus comprises: multiple antenna units arranged at intervals, multiple decoupling networks, a decoupling transmission line, and a grounding layer. The multiple decoupling networks correspond one-to-one to the multiple antenna units. Each decoupling network comprises a closed-loop structure, and a first transmission line and a second transmission line connected to the closed-loop structure. The closed-loop structure is provided with a first output port and a second output port. The first transmission line is used for being connected to a radio frequency chip. One end of the second transmission line is connected to the first output port, and the other end is connected to the corresponding antenna unit. The decoupling transmission line is connected between the second output ports of adjacent decoupling networks. The grounding layer and the multiple decoupling networks are stacked at intervals. A slot is formed in the grounding layer, and at least a part of the slot overlaps the closed-loop structures. The electronic device comprises the antenna apparatus.
