The invention discloses a multi-mode slot antenna and a mobile terminal. The multi-mode slot antenna comprises a metal plate, at least one isolating capacitor, at least two far-field feed structures, a near-field feed structure and a combiner feed matching circuit, wherein a slot is formed in the metal plate; two ends of the isolating capacitor are connected to two sides of the slot respectively, the slot is divided into a plurality of feed sections, each feed section is provided with a feed point, and one of the feed points is a first feed point; the far-field feed structures are arranged in a one-to-one correspondence manner with the feed points, and one of the far-field feed structures is a first far-field feed structure; the near-field feed structure and the first far-field feed structure share the first feed point; one end of the combiner feed matching circuit is connected with the first feed point, the first branch of the other end is connected with the first far-field feed structure, and the second branch is connected with the near-field feed structure. The far-field feed structures and the near-field feed structure share the feed points, so that an individual NFC antenna structure is omitted, the cost is reduced, and the structure is simple.
Description
technical field [0001] The invention relates to the field of antennas, in particular to a multimode slot antenna and a mobile terminal. Background technique [0002] With the continuous development of electronic technology and communication technology, mobile terminals have more and more functions, and there are more and more antennas that support mobile terminals to realize various data transmission and communication functions. , Near-Field Communications) antenna structure generally takes up a large space, and in order to avoid interference with other antenna signals, it is necessary to add an expensive ferrite with an area equivalent to that of the near-field antenna, which is expensive and complex in structure. Contents of the invention [0003] The invention provides a multi-mode slot antenna and a mobile terminal, which solve the problems of high cost and complicated structure of the NFC antenna structure in the prior art. [0004] In order to realize above-mentione...
