The invention provides an antenna structure and a mobile terminal. According to the antenna structure, a feed source and a matching circuit are arranged at the position on a first metal plate 0-2mm away from a slit, a first switch circuit is 0-3mm away from a first end of a first connection metal, the matching circuit is 0-3mm away from the first end of the first connection metal, the first switch circuit is 6-12mm away from a first edge of the first metal plate, and a second switch circuit is 25-35mm away from the first edge. Through the antenna structure, the first switch circuit and the second switch circuit are made to be in different switch states, so the antenna structure can correspond to different resonance frequency bands, and thereby problems of relatively narrow antenna bandwidth scope and relatively small coverage during reduction of antenna radiator dimensions in the prior art are solved.
Description
technical field [0001] The invention relates to the field of mobile terminals, in particular to an antenna structure and a mobile terminal. Background technique [0002] In recent years, mobile devices have been downsized as the demand for more compact mobile devices has grown. In this way, when the antenna is designed on the metal back cover of the mobile terminal, when the design size of the antenna radiator is reduced, the radiation impedance of the antenna will be reduced, resulting in narrowing of the antenna bandwidth, which in turn makes it difficult to achieve wide-band coverage of 700M-2700M in terms of antenna bandwidth. It is difficult to achieve all carrier aggregation on one antenna even with switches. For example, B39 (1880MHz-1920MHz)-B41 (2496MHz-2690MHz) carrier aggregation requires that the antenna can produce good radiation performance in the two frequency bands of B39 and B41 in a certain state, but the existing technical solutions are difficult to make ...
