<p>The present invention discloses an antenna and pertains to the field of communications technologies. The antenna includes: a printed circuit board, a first antenna feeding structure, a first antenna loading structure, and a first filter, where the first antenna feeding structure has a grounding pin and a feeding pin, the grounding pin and the feeding pin are separately connected to the printed circuit board, and the first antenna loading structure and a partial structure of the first antenna feeding structure form a coupling structure; and 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 configured to cut off a low-frequency current. A low-frequency current is cut off by using a filter, so as to implement selective filtering for an antenna loading structure and extend operating bandwidth of the antenna.</p> |
