Antenna structure and wireless communication device

Abstract

An antenna structure and a wireless communication device are provided, including a dielectric substrate, a first antenna, a second antenna, a third antenna, and a fourth antenna. The dielectric substrate includes a first surface and a second surface that are arranged opposite to each other; the first antenna, the second antenna, the third antenna and the fourth antenna are arranged on the first surface at intervals, the first antenna, the second antenna, the third antenna and the fourth antenna have different structures respectively. Each of the first antenna, the second antenna, the third antenna and the fourth antenna is respectively provided with a capacitor to respectively adjust a radiation path of the first antenna, the second antenna, the third antenna and the fourth antenna, so that the first antenna, the second antenna, the third antenna and the fourth antenna cooperatively radiate wireless signals of a preset frequency band. The radiation frequency of the antenna structure is convenient to adjust, and the design is simple and the size is small.
