Title:
ANTENNA APPARATUS AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/148004
Kind Code:
A1
Abstract:
An antenna design solution. A metal bezel of the electronic device and a PCB board is used for forming a slot, and by means of symmetric feed and antisymmetric feed, the slot can be excited to produce two slot antenna modes: a CM slot antenna mode and a DM slot antenna mode, so that high isolation and low ECC MIMO antenna characteristics can be implemented in a wide frequency band. Moreover, the two slot antenna modes share the same slot antenna radiator, so that antenna design space can be saved.
