Title:
ANTENNA DEVICE AND TERMINAL
Document Type and Number:
WIPO Patent Application WO/2020/133111
Kind Code:
A1
Abstract:
An antenna device, which may be applied to a terminal having a metal frame or a terminal having an all-metal ID. The antenna device may comprise: a slot antenna formed in a slot provided in a metal frame, and a groove antenna formed by a groove communicating with the slot. The groove may communicate with the slot at a middle portion at one side, and the groove may be provided on the metal frame of a terminal or on a PCB floor of the terminal. The present antenna device may have a plurality of antennas at the slot, has a simple structure, and belongs to a modular design, which is convenient for expansion. Especially when the groove is provided on the metal frame, the antenna device may be implemented at zero headroom as a dual-antenna pair of the same frequency or a plurality of antennas of other specifications suitable for a terminal that has an all-metal ID.
