Abstract

The invention discloses a Bluetooth antenna and a terminal. The Bluetooth antenna comprises an antenna body, wherein the antenna body is arranged on a printed circuit board; the antenna body comprises a first sub-antenna body and a second sub-antenna body which are in preset shapes; the first sub-antenna body comprises a first extending end extending on the printed circuit, a first connecting end connected with the second sub-antenna body and a matching part extending towards a preset direction; the matching part is used for realizing 50-ohm impedance matching; and the second sub-antenna body is connected to the first connecting end and extends to a preset position towards the first extending end. According to the embodiment of the invention, the antenna body is directly utilized to realize 50-ohm impedance matching, external elements are not needed, and a ceramic antenna is omitted, so cost is reduced.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a bluetooth antenna and a terminal. Background technique [0002] At present, Bluetooth technology has been widely used, especially on mobile phones, which has almost become a standard configuration. The implementation of Bluetooth antenna is generally a ceramic Bluetooth antenna, and there are also Bluetooth antennas made of metal sheets. [0003] However, the cost of the bluetooth antenna in the prior art is relatively high and the communication sensitivity cannot meet the usage requirements of current terminals. Contents of the invention [0004] Embodiments of the present invention provide a bluetooth antenna and a terminal, which are used to solve or at least partly solve the problems of cost and sensitivity of bluetooth antennas in the prior art. [0005] An embodiment of the present invention provides a Bluetooth antenna, including an antenna body, the antenna body is...
