Document Type and Number:

WIPO Patent Application WO/2019/129098

Kind Code:

A1

Abstract:

Provided are a multi-frequency antenna and a mobile terminal. The antenna comprises: a feeder line and a radiation unit connected to the feeder line; and further comprises a first notch structure located at one side of the radiation unit and in coupling connection with the radiation unit; a second notch structure located at the side of the first notch structure away from the radiation unit, and the one end of the second notch structure away from the radiation unit is grounded; and the first notch structure is optionally connected to the ground or the second notch structure, and when the first notch structure is connected to the second notch structure, the first notch structure is connected to the second notch structure through a first tuning device. In the technical solution, through the optional connection between the first notch structure and the second notch structure and between the first notch structure and the ground, the resonance of the notch structure itself can be improved, and furthermore the communication effects in different frequency bands of the antenna can be improved, improving the communication effect of the antenna.
