Embodiment Construction

[0025] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.

[0026] like figure 1 As shown, the mobile terminal antenna of the present invention has a pure metal antenna structure, including a metal frame 1, a system floor 2, a metal connection bar 1, a metal connection bar 2 4, a lumped inductor 5 and a coaxial feed port 6. Among them, the metal frame 1 is connected to the system floor 2 through the metal connecting strip 1 3 and the metal connecting strip 2 4, the lumped inductor 5 is welded on the metal connecting strip 2 4, and the outer conductor of the coaxial feed port 6 is welded to the system floor 2 On the top, the inner conductor straddles the gap and is welded on the metal frame 1 .

[0027] A three-dimensional view of the antenna of the present invention is as figure 2 As shown, the system floor 2 is a rectangular structure, and the metal frame 1 is a transparent cuboid structure, surround...

Abstract

A mobile terminal antenna employing a metal frame as a radiation body comprises the metal frame, a system floor, a first metal connection strip, a second metal connection strip, a lumped inductor anda coaxial feeding port, wherein the system floor is rectangular, a left side and a right side are long sides, an upper side and a lower side are short sides, the system floor is encircled by the metalframe, a gap exists between the metal frame and the system floor, the metal frame is connected with the first metal connection strip, the second metal connection strip and the system floor, the lumped inductor is welded onto the second metal connection strip, an outer conductor of the coaxial feeding port is welded onto the system floor, and an inner conductor crosses the gap and is welded onto the metal frame. The antenna is of a pure metal structure, no dielectric loss is generated, and high radiation efficiency is achieved; the metal frame is used as the radiation body, a traditional antenna structure is not needed, and the internal space of the mobile terminal is almost not occupied; and the mobile terminal antenna is applicable to various small-size mobile terminals with representative of a mobile phone.

Description

technical field [0001] The invention belongs to the technical field of antennas, in particular to a mobile terminal antenna using a metal frame as a radiator. Background technique [0002] With the rapid development of mobile communication, people are more and more accustomed to using mobile terminals to obtain various information. As a common form of mobile terminals, mobile phones have become one of the most popular electronic products in the world. In order to achieve high-speed wireless data transmission, mobile phone antennas need to have a wide bandwidth. For example, the fourth-generation mobile communication standard (4G) has eight frequency bands, including the low frequency band of 698-960MHz and the high frequency band of 1710-2690MHz. Designing mobile phone antennas to cover these frequency bands is a challenging task considering the strictly limited size of mobile terminals. On the other hand, people have more requirements for the appearance of mobile phones....
