Abstract

The invention discloses a multi-mode slot antenna and a mobile terminal. The multi-mode slot antenna comprises: a metal plate, wherein a slot is formed in the metal plate and used for dividing the metal plate into a ground end and an antenna end; at least two partition capacitors, wherein the two ends of the partition capacitors are connected with the two sides of the slot respectively, the slot is divided into a plurality of feed regions, and one of the partition capacitors is a shared partition capacitor; a combining feed matching circuit, wherein the combining feed matching circuit multiplexes the shared partition capacitor, and the combining feed matching circuit also comprises a capacitor C, an inductor L and an inductor L1; at least two far field feed structures, wherein one far field feed structure is a first far field feed structure, and the first far field feed structure is connected with the other end of the capacitor C; and a near field feed structure, wherein the near field feed structure is connected with the other end of the inductor L. According to the multi-mode slot antenna, the slot is shared through a near field communication structure and a far field communication structure; and the multi-mode slot antenna is simple in structure and low in cost.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of antennas, and in particular to a multi-mode slot antenna and a mobile terminal. Background technique [0002] With the continuous development of mobile terminals and wireless communication technology, NFC (Near Field Communication, near-field communication) technology, as a short-range high-frequency wireless communication technology, can realize electronic payment, Functions such as intelligent identification and data transmission, NFC technology has also been widely used due to its above-mentioned unique advantages. [0003] The NFC antenna installed on the mobile terminal generally occupies a large volume, and in order to avoid mutual interference with the far-field communication antenna in the mobile terminal, it is necessary to add an expensive ferrite with a comparable area to the NFC antenna. With the increase of wireless communication functions of mobile terminals, more ...
