Abstract

The invention discloses an antenna, which belongs to the technical field of communication. The antenna includes: a printed circuit board, a first antenna feeding structure, a first antenna loading structure and a first filter, the first antenna feeding structure has a ground pin and a feed pin, and the ground pin and the feed pin The pins are respectively connected to the printed circuit board, and the first antenna loading structure and a part of the first antenna feeding structure form a coupling structure; the first antenna loading structure is connected to the first filter , the first filter is connected to the printed circuit board, and the first filter is used to cut off low-frequency current. The filter cuts off the low-frequency current to realize the selective filtering of the antenna loading structure and expand the working bandwidth of the antenna.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to an antenna. Background technique [0002] With the development of communication technology, terminal devices send and receive signals through built-in antennas to realize real-time communication. The development of LTE (Long Term Evolution, Long Term Evolution) has higher and higher requirements on the bandwidth of the antenna, completely covering all frequency bands of 2G, 3G, and 4G, which brings great challenges to antenna design. [0003] Built-in antennas in the form of monopoles, IFAs, and PIFAs are widely used in existing terminal equipment. These built-in antennas and PCBs together form a radiator for receiving and sending signals, which optimizes the performance of the antenna. [0004] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0005] In the prior art, built-in antenna...
