Document Type and Number:
WIPO Patent Application WO/2020/228399
Kind Code:
A1
Abstract:
Disclosed in the embodiments of the present invention is an antenna device. The antenna device comprises a ground plane, a monopole, a first feed unit and a second feed unit. Slots in the ground plane comprise a first slot and a second slot communicating with each other, and the second slot extends from the first slot to an edge of the ground plane. The monopole comprises a first branch and a second branch, the second branch extends from the first branch to the second slot, and the second branch and the second slot constitute a feed structure. The first feed unit is electrically connected to the ground plane, serves as a feed structure for feeding, and is used for exciting a first radiation mode of the antenna device, in which mode the first slot and the ground plane are radiators. The second feed unit is electrically connected to the second branch, serves as a feed structure for feeding, and is used for exciting a second radiation mode of the antenna device, in which mode the second branch and the ground plane are radiators. The two radiation modes are polarized orthogonally. By adopting the antenna device, a plurality of antennas may be arranged in a limited small-sized space, the performance is excellent, and the insulation is good.
