[0059] In other implementation manners, the two modes of the antenna device may also work in different frequency bands. For example, the first radiation mode works in the first frequency band, and the second radiation mode works in the second frequency band. Optionally, the first frequency band may include a Wi-Fi frequency band, and the second frequency band may include a Wi-Fi frequency band and a GPS frequency band. For example, the antenna device can stimulate the slot to generate 2.4GHz Wi-Fi resonance (the first frequency band is the 2.4GHz Wi-Fi frequency band), and can also stimulate two resonances of GPS L1 and 2.4GHz Wi-Fi (the second frequency band includes 2.4GHz Wi-Fi Wi-Fi frequency band and GPS L1 frequency band). Not limited thereto, the first frequency band and the second frequency band may also be other frequency bands.

The embodiment of the invention discloses an antenna device, which comprises a floor, a monopole, a first feed unit and a second feed unit, and is characterized in that a slot on the floor comprises afirst slot and a second slot which are communicated with each other, and the second slot extends from the first slot to the edge of the floor. The monopole comprises a first branch knot and a secondbranch knot, the second branch knot extends into the second slot through the first branch knot, and the second branch knot and the second slot form a feed structure. The first feed unit is electrically connected to the floor and realizes feeding as a feed structure, and is used for exciting a first radiation mode of the antenna device, and in the first radiation mode, the first slot and the floorare taken as radiators. The second feed unit is electrically connected to the second branch knot, realizes feeding as the feed structure and is used for exciting a second radiation mode of the antennadevice, and in the second radiation mode, the second branch knot and the floor are taken as radiators; the two radiation modes are polarized orthogonally. By adopting the antenna device, multiple antennas can be arranged in a limited small-scale space, the performance is excellent, and the isolation degree is high.
Description
technical field [0001] The present invention relates to the technical field of antennas, in particular to an antenna device applied in a terminal. Background technique [0002] With the development of mobile communication technology, multiple input multiple output (multi input multiple output, MIMO) antenna technology, such as high-fidelity wireless multiple input output (wireless fidelity MIMO, Wi-Fi MIMO) antenna, is more and more widely used in terminals. , the number of antennas has doubled, covering more and more frequency bands. The recent trend in terminal design is a higher screen-to-body ratio, more multimedia devices, and larger battery capacity. These designs have sharply compressed the antenna space. How to layout multiple antennas in a limited design space is a very challenging problem. Moreover, the antenna layout also needs to consider the industrial design (ID) of the terminal product, such as metal ID, full-screen ID, etc., which further increases the diff...
