Embodiment Construction

[0022] The following are the best embodiments of the full metal housing antenna device described in the present invention, which do not limit the protection scope of the present invention.

[0023] refer to figure 1 and figure 2 , the figure shows an all-metal housing antenna device, which includes a metal housing 1 mounted on the back of the communication device, a PCB main board 2, antenna branches and feed points 3, 4. Such communication devices include cell phones, PDAs, portable computers and similar devices.

[0024] In this embodiment, the metal casing 1 is provided with a metal frame 14 extending from the back to the side of the communication device at the surrounding edges. Except for the front screen, the side and the back of the communication device are all metal, which improves the metal texture of the whole machine. At the same time, the metal frame 14 can become a part of the antenna, which increases the frequency band coverage of the antenna.

Abstract

The invention discloses an antenna device for a full metal shell. The antenna device comprises a metal shell arranged at the back of communication equipment, antenna branches and feeding points, wherein a metal frame extending from the back of the communication equipment to the side face is arranged around the periphery of the metal shell; the metal shell is segmented and separated into a first metal shell, a second metal shell and a third metal shell; the feeding points are respectively positioned between the first metal shell and the second metal shell and between the second metal shell and the third metal shell; an antenna branch I arranged at the first metal shell and an antenna II arranged at the third metal shell are respectively connected with a radio-frequency signal source of a PCB (Printed Circuit Board) mainboard arranged on the second metal shell, and signals are correspondingly fed in the first metal shell and the third metal shell through the feeding points. With a three-section type full metal shell structure, the metal frame becomes a part of the antenna, the first metal shell and the third metal shell can be used as antennas at the same time, and the antenna device has the advantages of ultra-wide low-frequency band width and high-frequency band width.

Description

technical field [0001] The present invention relates to the technical field of antenna devices for communication equipment, and more specifically, relates to an antenna device with a full metal casing. Background technique [0002] At present, some communication devices (such as mobile phones) use all-metal shells. Except for the front screen, the sides and back of the whole machine are made of metal, which makes the whole machine full of metal texture, greatly enhances the appearance expressiveness, and can also be greatly enhanced. Structural strength. However, the all-metal housing will bring great difficulties to the antenna design, and the traditional antenna forms such as PIFA, IFA, Monopole, and loop have been difficult to realize. Usually, digging out the metal in the antenna area and covering it with non-metallic materials, so that the antenna can radiate energy, is a commonly used solution at present. However, digging out the metal in the antenna area not only aff...
