Embodiment 1

[0177] In Example 1, for the strip conductor, two desired eigenmodes can be excited through the feeding design. The two expected characteristic modes are: Figure 2A-Figure 2B The CM wire antenna pattern shown, Figure 3A-Figure 3B DM wire antenna pattern shown. That is to say, through the feeding design of the strip conductor, the CM line antenna mode and the DM line antenna mode can be selected from various characteristic modes of the strip conductor.

Abstract

The invention relates to an antenna device and electronic equipment. According to the antenna design scheme, a conductor (such as a strip-shaped conductor and a slotted conductor) with a specific shape is subjected to single-feed design so as to excite a plurality of antenna modes. For example, a CM line antenna mode and a DM line antenna mode can be excited by feeding the strip-shaped conductor. For example, the design of feeding one slotted conductor can feed a CM slot antenna mode and a DM slot antenna mode. According to the antenna design scheme, the miniaturization of the antenna can be realized, and a plurality of frequency bands can be covered at the same time.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to an antenna device applied in electronic equipment. Background technique [0002] Multiple-input multiple-output (MIMO) technology plays a very important role in the fifth generation (5thgeneration, 5G) wireless communication system. However, it is still a big challenge to obtain good MIMO performance for mobile terminals, such as mobile phones. One of the reasons is that the very limited space inside the mobile terminal limits the frequency band and high performance that the MIMO antenna can cover. Contents of the invention [0003] An embodiment of the present invention provides an antenna device, which can cover more frequency bands while realizing miniaturization of the antenna. [0004] In a first aspect, the present application provides an electronic device, where the electronic device includes an antenna device. The antenna device may include: a strip conductor, on wh...
