Embodiment 1

[0069] In this embodiment, the metal frame of the electronic device (such as a mobile phone) is designed as an antenna, and the antenna may be called a metal frame antenna. Open gaps on both the side metal frame and the bottom metal frame, and separate power feeds to the side metal frame and the bottom metal frame according to different scenarios, so as to realize switching between portrait mode and landscape mode.

Such as Figure 4A-Figure 4C As shown, the antenna device may include: a side metal frame 11-1, a bottom metal frame 11-7, a power feed 23, and multiple ...

Embodiment 2

[0088] In this embodiment, under the condition that gaps are opened on both the side metal frame and the bottom metal frame, the metal frame is adjusted by changing the state of the tuning switch connected to the metal frame (such as on (on) state or off (off) state). Whether the radiation mode of the antenna is a horizontal mode or a longitudinal mode, so as to take into account both free space radiation efficiency and hand-held radiation efficiency. The tuning switch can be switched to an on state by cutting 0 ohm to ground, so the on state can also be called a ground state. A tuning switch in the off state can be used for frequency tuning.

Abstract

An antenna device is composed of a metal frame of an electronic device. The free space radiation efficiency and the handheld radiation efficiency are balanced by forming gaps in a bottom metal frame and side metal frames. In a free space scene, the longitudinal mode of the antenna is strong, and the radiation efficiency of the free space is good. When the electronic equipment is held by hand, thetransverse mode of the antenna is strong. The handheld radiation efficiency is good.

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] In order to enhance the sense of quality of mobile electronic devices (such as mobile phones), metals are increasingly applied to the industrial design (industry design, ID) of mobile electronic devices, such as metal frames. In the industrial design using a metal frame, designing the metal frame as an antenna becomes an antenna design direction. [0003] In the prior art, a slit with a small width (for example, 1 mm to 1.5 mm) is provided on the metal frame, and the slit will separate the metal frame into multiple parts, thereby forming multiple metal frame antennas. When the metal frame is in an open environment, there is air outside the metal frame, and the radiation performance of the metal frame antenna is good. However, when the human body touches the gap on the metal frame, such as holding ...
