Abstract

The invention discloses an antenna comprising a metallic frame continuously arranged on the outer side of a mobile communication device, a grounding portion located in the mobile communication device and disposed apart from the metallic frame, a first feed portion arranged on a side of the mobile communication device and connected with the metallic frame and the grounding portion, and a first control portion controlling the first feed portion. The grounding portion is provided with a first connection portion and a second connection portion which are connected with different positions of the metallic frame. A first antenna is defined by the metallic frame, the first feed portion, the grounding portion, and the first connection portion. A second antenna is defined by the metallic frame, the first feed portion, the grounding portion, and the second connection portion. The antenna further comprises a third antenna, a first switch circuit connected with the third antenna and the grounding portion, and a second control portion controlling the first switch circuit. The third antenna is arranged between the metallic frame and the grounding portion. The second control portion control the first switch circuit so as to control the operating state of the third antenna.

Description

【Technical field】 [0001] The invention relates to an antenna, in particular to a mobile phone antenna. 【Background technique】 [0002] The mobile phone with metal frame feels good and meets the aesthetic requirements of users. It is the technology chosen by many brand manufacturers for their flagship products. At the same time, the metal frame can be used as a part of the antenna, so more and more mobile phone frames are used as part of the antenna. . However, due to the limitation of antenna technology, metal-frame mobile phones are usually provided with breakpoints, and the breakpoints affect the appearance of the mobile phone. Therefore, it is rare to see a mobile phone with a full metal frame in the market. [0003] Chinese patent announcement No. CN201420551405 discloses a closed-loop (seamless) metal frame 3G antenna, which can realize working frequency bands of 824MHz-960MHz and 1710MHz-2170MHz. [0004] Please refer to figure 1 As shown, the closed-loop metal fram...
