Abstract

The embodiment of the invention provides an antenna which comprises a metal shell and at least one feed source. The antenna further comprises a low-frequency matching circuit, a high-frequency matching circuit, a low-frequency feed point and a high-frequency feed point; a gap is formed on the metal shell, the gap divides the metal shell into an antenna radiation arm and main reference ground, one side edge of the metal shell is provided with a fracture, and the gap is communicated with the fracture; one end of the low-frequency matching circuit is connected with the other end of the feed source, the other end of the low-frequency matching circuit is connected with the low-frequency feed point, and the low-frequency feed point is positioned in the gap or at the position of the antenna radiation arm; and one end of the high-frequency matching circuit is connected with the other end of the feed source, the other end of the high-frequency matching circuit is connected with the high-frequency feed point, and the high-frequency feed point is positioned at the position of the antenna radiation arm. By separating the low-frequency matching circuit and the high-frequency matching circuit of the antenna excellent antenna performance in a wide frequency band can be achieved, and the antenna is excellent in both bandwidth and efficiency.

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] The wide-band antenna of the metal body of the existing mobile terminal includes a slot and a feed source. Among them, the low-frequency radiation mode and the high-frequency radiation mode are switched by switching the effective length of the slot (that is, the antenna radiator path length). Therefore, the adjustable range of the matching circuit in the prior art is limited, and the matching method is limited by different radiation modes. , therefore, different radiation modes need to share the matching circuit, making the bandwidth and efficiency of the antenna poor. Contents of the invention [0003] An embodiment of the present invention provides an antenna to solve the problem in the prior art that different radiation modes of the antenna share a matching circuit so that the bandwidth and efficiency ...
