Abstract

An embodiment of the invention discloses a terminal antenna and an intelligent terminal. The terminal antenna comprises a first antenna, a first feed source, a first matching circuit, a first switch, a second matching circuit and a third matching circuit, wherein a first port of the first antenna is connected with the first feed source through the first matching circuit; the first matching circuit is used for matching the first antenna; the second matching circuit comprises a plurality of matching channels and is used for spreading a spectrum of a high frequency band of the first antenna; a second port of the first antenna is connected with the plurality of matching channels of the second matching circuit through the first switch; a third port of the first antenna is connected with a third matching circuit; the third matching circuit is used for spreading a spectrum of a low frequency band of the first antenna. With adoption of the scheme of the embodiment, overall space of the terminal is reasonably used, and multi-frequency band and large bandwidth of the antenna in the terminal are realized.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a terminal antenna and an intelligent terminal. Background technique [0002] With the continuous development of science and technology, smart terminals such as mobile phones have become one of the indispensable tools for daily use due to their rich functions and strong display effects. [0003] At present, fingerprint functions such as fingerprint unlocking and fingerprint payment have gradually become common functions of smart terminals. In some mobile phones, the fingerprint identification module is set on the front of the mobile phone and integrated with the Home button to improve user experience. However, this layout will bring some changes to the design of the whole machine. For example, the display drive circuit needs to be set at the top of the display screen, and the headphone jack needs to be set at one end of the terminal’s Home button. These cha...
