Problems solved by technology

In the prior art, the metal middle frame generally adopts high-strength aluminum alloy, magnesium alloy or stainless steel, etc. However, for the metal middle frame of the above materials, the increase in strength is mainly achieved by increasing the structural size of the metal middle frame, which means It will cause the metal middle frame to occupy the clearance of the antenna, which will reduce the performance of the antenna

Embodiment Construction

[0064] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

[0065] Such as Figure 1-2 As shown, the first aspect of the present invention provides an antenna, including a PCB board and a metal middle frame 1, the PCB board includes a floor layer, the metal middle frame 1 includes a first ring frame 11 and a second ring frame 12, the first ring frame A radiator is formed on the frame 11, and the second annular frame 12 is electrically connected to the floor layer to form a system ground of the antenna.

[0066] The metal middle frame 1 is an amorphous conductor, which has high strength and is not easily deformed even if its structural size is small. As an amorphous conductor, it can be used as an antenna by forming a metal structure through a simple process The branch structure can increase the electrical length of the radiator, thereby broadening the frequency band of the antenna.

Abstract

The invention relates to an antenna and a mobile terminal. The antenna comprises a printed circuit board (PCB) and a metal middle frame, wherein the PCB comprises a floor layer, the metal middle frame is an amorphous electric conductor and comprises a first annular frame and a second annular frame, the second annular frame is electrically connected with the floor layer, the first annular frame and the second annular frame are both strip-shaped frames, the second annular frame is sleeved with the first annular frame, a length direction of the second annular frame extends along a width direction of the first annular frame, an included angle between a plane encircled by the first annular frame and a plane encircled by the second annular frame is nonzero, and a radiation body is formed on the first annular frame. By the scheme, the strength of the metal middle frame is improved, the clearance space of the antenna is expanded, and the performance of the antenna is improved.

Description

technical field [0001] The present invention relates to the technical field of antennas, in particular to an antenna and a mobile terminal. Background technique [0002] Portable devices such as mobile phones and tablet computers are equipped with antennas to receive and transmit electromagnetic wave signals to realize wireless communication. [0003] Taking a mobile phone as an example, for a mobile phone with a glass back shell, because the glass is fragile, a metal middle frame with sufficient strength is usually required as a support to provide support for the electronic devices in the mobile phone. In the prior art, the metal middle frame generally adopts high-strength aluminum alloy, magnesium alloy or stainless steel, etc. However, for the metal middle frame of the above materials, the increase in strength is mainly achieved by increasing the structural size of the metal middle frame, which means It will cause the metal middle frame to occupy the clearance space of t...
