Combined Antenna System and Mobile Terminal

Abstract

Provided are a combined antenna system and a mobile terminal. The combined antenna system and a metal rear housing of the mobile terminal are used cooperatively, wherein the metal rear housing comprises a bottom plate and a side plate and an end plate which are respectively connected to the bottom plate. The combined antenna system comprises: two stereoscopic coupled antennas, which respectively have a first metal wiring that can generate low frequency resonance and a second metal wiring that can generate high frequency resonance, wherein the stereoscopic coupled antennas are connected to a radio frequency feed source of the mobile terminal, and the stereoscopic coupled antennas are located at an included angle constituted by the bottom plate, the side plate and the end plate, and respectively have a first gap, a second gap and a third gap with the bottom plate, the end plate and the side plate, so that the stereoscopic coupled antennas simultaneously perform coupled feeding with the bottom plate, the end plate and the side plate. The combined antenna system provided in the present invention can be applicable to a metal rear housing, and the product is enabled to flexibly and conveniently tune various frequency bands via a structure design, thereby reducing the radiation loss of the product, so that the product can meet performance requirements of future mobile terminals with various network standards.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a combined antenna system and a mobile terminal with the combined antenna system. Background technique [0002] In the mobile terminal equipment industry such as mobile phones and tablet PCs, with the continuous improvement of user experience requirements for the appearance and feel of products, metal decorative mobile products with good touch and excellent wear resistance have become the mainstream of consumption in this industry However, since the unique shielding performance of the metal back shell and metal frame and other decorations will seriously reduce the reliability of the antenna, therefore, while conforming to the product development trend, higher requirements are put forward for major manufacturers in the design of the antenna.

[0002] In the mobile terminal equipment industry such as mobile phones and tablet PCs, with the continuous improvement of user experience requirements for the appearance and feel of products, metal decorative mobile products with good touch and excellent wear resistance have become the mainstream of consumption in this industry However, since the unique shielding performance of the metal back shell and metal frame will seriously reduce the reliability of the antenna, therefore, while conforming to the product development trend, the major manufacturers put forward higher requirements on the design of the antenna. Require

[0003] In order to solve this technical problem, in the prior art, a non-metallic area is usually arranged on a large area on the metal back cover to reduce its interference to the signal, but this structure also reduces the quality of the product accordingly, which is not conducive to product promotion; the prior art In another solution, the shrapnel is set on the inner side of the antenna system, and it is matched with the metal back cover by direct feeding to realize the coexistence of it and the metal in a large area, but this structure has disadvantages such as the shrapnel is fragile, The reliability of the antenna is reduced, and because the structure is not easy to adjust the resonant frequency of the antenna, the radiation efficiency of the product is greatly reduced
